Dell PowerScale (Isilon) Reviews

I use the solution in my company for unstructured data storage.

The most valuable features of the solution are Isilon InsightIQ for reporting issues and the extra ransomware protection features.

In my company, we have lots of huge amounts of data, around several petabytes, so we needed a way to have some responsive clusters with failover. In our company, we also have to give some reports to get some upgrades for the clusters recently as it is easier for us if we can give a look out to the management about how much research is done by us and how much space is required to do research. Our company has several tech people in our research facilities in Germany at the moment, and we have lost a lot of data to ransomware. One of the key features my company expects from the product is that it reduces ransomware attacks.

Dell PowerScale (Isilon) offers a sense of resilience, cyber resiliency, and security to my organization, especially with the third-party add-ons.

In terms of the benefits we experienced from the use of the product, I would say that our organization has different researchers. In our company, we have every operating system in use for different workloads. I can imagine that when our company deals with file-sharing features, the tool is way easier to use, and we can perform the procedure smoothly. The tool is also easy to deploy.

In terms of my experience with Dell PowerScale (Isilon) and its licensing part, cost of implementation, and costs of ownership, I don't have much information because our company has only been using the tool for over a year. The documentation is easy, and the management is easy and fast, so my company has had a really good experience with the tool.

The cost of ownership of Dell PowerScale (Isilon) is good because our company is able to save a lot of energy, especially in terms of manpower and electricity. My company has managed to get down from four racks to half a rack.

Dell PowerScale (Isilon) has helped reduce and eliminate data silos, and it has helped our company shut down several single data storages. In our company, we had an old Dell PowerVault MD Storage, and through the PowerScale OneFS cluster, we could shut down a lot of network-attached storage devices. My company wants to consolidate everything into a central data storage and be able to manage our small team.

Based on the assessment of the tool's flexibility for supporting various data workloads while keeping them protected, I would say that we are in the process of migration. My company is in the process of migrating some video data and so on, but as of now, we use the product's services in the backend for containerization.

The product has helped reduce overall risk in my company since we just have one cluster to manage. Primarily, it is easier to have an overview and keep the clusters up to date.

When envisioning the future of our containerized solutions in terms of cloud integration, I see that in Germany considering a fully cloud-based approach can be hard. Mostly, Germans don't like to put any data on the cloud. I believe that users may opt for a private cloud or a hybrid strategy.

Based on a few key factors and the decision-making process, I would say that my company would choose an environment that offers the most amount of security features for our containerized applications since we have research data while sometimes, we also have data that is used for thesis, so there are areas where we can't afford anyone to get access to our data.

There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities. Our company has to buy another third-party software deal with tape backup. 

It is a little hard to implement Dell PowerScale CloudPools. In our company, we would like to have another storage tier for data access, but it is getting too expensive when it comes to the licensing part of the product.

Sometimes, it can be bothersome to get through from the first level of support to the second one and from the second level to the third level of support. To deal with a set of similar errors, it would be great if Dell could allow users to skip some support stages. The reason a user may be forced to go through different levels of support can be because there is no automated support available to be offered.

I have been using Dell PowerScale (Isilon) for over a year. My company is a customer of the tool.

My company has never had any issues with the stability of the product.

The product's scalability feature is super easy to use.

My company has used the technical support of the tool. I rate the technical support a ten out of ten.

Positive

My company deals with big companies that offer storage solutions. My company does not have similar products from different vendors, so we deal with different vendors and provide different solutions for different scenarios.

The product's initial setup phase was really easy because our company had technicians coming over. I feel the technicians could do better, and so now my company has a new support partner who installs the hardware. At the time our company purchased Dell PowerScale (Isilon), we had a third-party company install the product in our company. Our organization called in a third-party company to introduce us to how to install Dell PowerScale (Isilon). There were some issues after the tool's setup phase that had to be fixed, and so it got quite a little messy because of the aforementioned problems.

We received several good recommendations from partners of our organization in Germany, after which we dived into Dell PowerScale (Isilon), considering that my company is in the commercial research area, where we have to deal with contracts. My company believes that if we have contracts with Dell, then it would be easier for us to process data. The last time our company upgraded our compute, we entered into another contract with another vendor, which was not good. My company is looking into entering into more contracts with Dell.

Considering the product still needs to add a few features, I rate the overall tool a nine out of ten.

I rely on Dell PowerScale to manage and store manufacturing data from NES systems. It is great for handling big data, offers scalability, and ensures data security, simplifying the storage and retrieval of manufacturing information.

The most valuable features of Dell PowerScale for its reliable performance and stability. The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice. It is a top pick for my customers due to these qualities.

There is room for improvement in its handling of object storage. While it excels in managing file systems, enhancing features for more efficient handling of objects could make it even better, ensuring faster and smoother operations.

I have been working with Dell PowerScale for ten years.

The technical support is very good. They are quite helpful.

The installation is quite simple and the deployment takes only a few hours. In my organization, we have a total of 26 system engineers, and among them, 11 are trained to handle Dell PowerScale. These engineers are responsible for installing, maintaining, and providing support for the product. We conduct maintenance regularly, typically with a focus on remote support, offering 24/7 assistance. For on-site support, our goal is to respond within four hours.

While customers often perceive it as expensive, I find that considering its functions and performance, Dell PowerScale is reasonably priced. I would rate it as a five out of ten in terms of costliness. In addition to the standard licensing fee, there are extra costs for services and additional solutions with Dell PowerScale. Services like maintenance and support may incur charges. Sub-solutions such as CloudIQ are also additional and may be charged based on usage or quota.

I would highly recommend Dell PowerScale to others. Overall, I would rate it as a nine out of ten.

We use the solution for unstructured data storage.

The solution has centralized file storage at the scale it does that.

The solution is a complete package, but its most valuable feature is the DR capabilities replication.

I would like to see PowerScale become a multi-site active-active solution. I would like to see increased reporting and statistics functionalities.

I've used the solution for at least six years now.

Based on the last three years, I rate the solution's stability a nine out of ten. The stability has been very good.

I rate PowerScale's scalability an eight out of ten.

Before PowerScale, I more or less just used Windows file servers.

The initial setup is moderately easy.

I have seen a return on investment.

Our company finds the pricing high, but it decreases over time.

We looked at NetApp.

My advice before choosing PowerScale is to take training up front on it because it has a lot of capabilities. Do some good training before you try to deploy it. I rate PowerScale an eight out of ten.

We use the solution for NFS. 

Dell PowerScale's performance is good. 

The product needs to improve CLI since commands are complex. The search option is also difficult since you must give the full path. 

I have been using the product for more than three years. 

Dell PowerScale is stable. 

My company has more than 1000 users for the solution, and it is scalable. 

Dell PowerScale's support is good. 

Positive

Dell PowerScale's deployment is complex. 

I rate Dell PowerScale a nine out of ten. 

We're using 95% of data for user access and 5% percent for the NFS mount point. We're a startup and customer of Dell. 

It's helpful that we're able to scale the number of nodes without having to build additional clusters. We started with a very small footprint and now we have 30 nodes and recently expanded an additional eight nodes on the cluster. We can create multiple storage pools from this if we decide to add a location within the cluster itself.

We're struggling to find the NIXI protocol. It's for people needing to access using Windows and Linux. We're struggling with the UID mapping and how to configure mapping-related things. I'm looking at how to map those GIDs and UIDs. 

I've been using this solution for four years. 

The solution is stable. If it's being used for the NAS protocol, it's very stable.

The solution is very scalable. 

We have direct Dell support only.

The initial setup is straightforward. We have 4,000 users in the company who are accessing the shared drive without any problems. Maintenance can be done by one person. 

We have a five-year contract with Dell. We get new hardware each time we renew the contract and the cost is calculated on a percentage-wise and scalability basis. Every five years, we replace the tech nodes. 

If you're looking for a product to use for an assembly protocol, this is the best solution on the market.

I rate this product nine out of 10. 

The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol.

Dell PowerScale (Isilon) could improve the load distribution capability. For example, in some cases, the system load is not distributed automatically on all the nodes but is concentrated only on one. You have a peak request on only one node and the others don't do anything.

In an upcoming release, the solution should have security features embedded, not external software.

I have been using Dell PowerScale (Isilon) for approximately nine years.

Dell PowerScale (Isilon) is a reliable solution.

Dell PowerScale (Isilon) is scalable. It is easy to expand capacity.

Most of our customers are enterprise-sized companies and the solution is suitable only for companies with a lot of data. For example, you can have a start-up company dealing with a large amount of data, but only have 10 people working on it. In this case, you will need a solution with this capability.

I am satisfied with the support.

If you have used the solution previously then the initial setup of Dell PowerScale (Isilon) is easy, if not then it is difficult. If you have good planning and preparation then the implementation can take two to three days.

We do the implementation of this solution for our customers.

The price of Dell PowerScale (Isilon) is reasonable.

My advice to others is they should work with a provider that knows the solution well and the features in order to implement it correctly.

This is a good solution but it is not always the best choice, it depends on the use case.

I rate Dell PowerScale (Isilon) an eight out of ten.

PowerScale (formerly Isilon) is effectively a giant NAS. We have two clusters, one for production workloads and one for Disaster Recovery and Business Continuity purposes. These clusters are installed in separate data-centers, physically located in two different places in the country. Both clusters were deployed at the same time when we first adopted the solution, and we have been growing them at an almost equal rate ever since.

Our production cluster is attached to our High-Performance Computing (HPC) environment, and this was the primary use case in the beginning: to provide scale-out storage for the Bioinformatics team, who do omics analysis on plant and seafood organisms that we do scientific research on. As time went on, we expanded our use of the platform for other user groups in the organization.

Eventually, PowerScale became the de-facto solution for anything related to unstructured data or file-based storage. Today, we also use the platform to host users’ home directories, large media files, and really any kind of data that doesn't really fit anywhere else, such as in a SharePoint library or a structured database. Nowadays, almost everyone in the organisation is a direct or indirect user of the platform. The bulk of the storage, however, continues to be consumed by our HPC environment, and Bioinformaticians continue to be our largest users. But we also have data scientists, system modellers, chemists, and machine-learning engineers, to name a few. 

Our company has multiple sites throughout the country and overseas, with the two primary data-centers supporting our Head Office and most of the smaller sites. Some of these sites, however, have a need for local storage, so our DR/BCP PowerScale cluster receives replicated data from both our production cluster as well as these other file servers.

Before PowerScale we used to have a different EMC product. I believe it was VNX 5000, which is primarily a block storage array with some NAS functionality. We did not have a HPC environment, however we did have a group of servers that performed approximately the same function.

Back in those days, raw storage had to be partitioned into multiple LUNs, and presented as several independent block devices because of size limitations of the storage array. When one of these devices started to run out of space, it was extremely cumbersome and time-consuming to shift data away from it, which slowed down our science. We wanted a solution that would free our users from the overhead of all of that data wrangling. Isilon was a good fit because it enabled us to effectively consolidate five separate data stores into a single filesystem, providing a single point of entry to our data for all of our users.

PowerScale helped us consolidate our former block storage into a full-fledged, scale-out, file storage platform with great success. We then decided to expand our use cases further, replacing some of the ancillary Windows File Servers that provided network file shares in our Head Office. We now have a single platform for all our unstructured data needs at our main locations.

We have not explored using PowerScale cloud-enabling features yet, but it is in our roadmap. The fact that those features exist out of the box, and can be enabled as required is another reason the platform is so versatile.

The switch to PowerScale was transformative. Before we implemented it, users had to constantly move their data between different storage platforms, which was time consuming and a high barrier of entry for getting the most of our centralized compute. Distributed, parallel processing is challenging enough, to add data wrangling on top of it created massive cognitive overload. Scientists are always under pressure to deliver on time, and deadlines are unforgiving. The easier we can make leveraging technology for them, the better.

We officially launched our current HPC environment shortly after we introduced Isilon, supporting approximately 20 users. Today, that number has grown 17500% to over 350 users across all of our sites. In an organization with nearly 1,000 employees, that's more than a third of our workforce! I credit PowerScale as one of the critical factors responsible for that growth. PowerScale simplified data management because it allows you to present the same data via multiple different protocols (eg: SMB, NFS, FTP, HTTP, etc), tremendously reducing our users’ cognitive overhead.

Before adopting PowerScale, we also faced capacity constraints in our environment. I had to constantly ask end-users to clean up and remove files they no longer needed. Our block data stores were constantly sitting at around 90% utilization. Expanding the storage array was not only expensive: every time that we wanted to provision additional space we had to decide if it was justified to re-architect the environment versus adding yet another data store. And going with the later option meant going back to our users again to free up space before more capacity could be added. All of this wasted massive amounts of time, that could have otherwise been spent running jobs and doing science.

Once we introduced scale-out storage, capacity upgrades and expansion became straightforward. The procurement process was simplified because now we can easily project when we will hit 90% storage utilization, and our users have visibility of how much storage they are individually consuming thanks to accounting-only quotas, which help keeping storage usage down. PowerScale provides a lot of metrics out of the box, which are easy to navigate and visualize using InsightIQ, and most recently DataIQ.

I can certainly recommend PowerScale for mission-critical workloads, it is a powerful but simple platform with little administration overhead. We use it in production for a variety of use cases, and it would be hard for our organization to operate effectively without it.

When we selected Isilon as our preferred storage provider, many considerations came into play, but the deciding factor was how little administration it requires. We no longer need a dedicated storage administrator looking after it. Instead, our Systems Engineers can handle the day-to-day operations without requiring in-depth expertise in storage management. The simplicity of the solution was a strong selling point when we first started looking into it. For example, when you have replicated clusters, you must ensure that you can actually failover between them in the event of a disaster. PowerScale makes setting up and checking the status of replication schedules extremely simple.

Over time, we started using more and more of its capabilities. I believe the most valuable feature we started using, beyond the initial scope for the solution, is the multi-protocol system that allows you to access the same set of files using different network protocols like NFS or SMB. PowerScale’s Unified Permission Model ensures that data security and access permissions are honoured regardless of whether the client is a Windows desktop or a Linux server. Our users can now access the data they need for their research, without having to deal with multiple credentials depending on the environment they are using, or having to rely on specific clients. The same file can be opened and edited from Windows Explorer or from the Linux command line, and we can guarantee that the ownership and permissions of that file will remain consistent. It reduces friction and cognitive overhead, which is what I value the most.

Data security and availability are also included in solution, out-of-the-box. Of course you still need to be aware of how to configure the different features to your use case, but from a data security and availability perspective, you can leverage replication schedules, snapshotting, increased redundancy at rest, and all of those features which we now consider a must-have. With PowerScale, I can have piece of mind that if a specific directory needs to be protected, it will be protected.

The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB. You can either access a file because it can be access by anyone in the organization, or you cannot at all. There is no in-between. HTTP is not considered a first-class data access protocol, so the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply.

However, with the recent introduction of S3 starting from OneFS 9, I believe the necessary plumbing is already there for HTTPS to also be elevated to a first-class protocol in the future because both protocols sit behind a web server under the hood. It does not sound like it would be too complicated to implement, but it would be a valuable feature and it is currently missing.

We started exploring storage solutions for our environment back in 2012. We have been using PowerScale for nearly 10 years now.

PowerScale has never failed us. Since it was first installed, it has been running with almost 100% uptime since we started using it. We have only had to shut down the entire cluster once because we were moving data-centres. In earlier versions, sometimes you had to reboot the entire cluster for significant OS upgrades. Today, rolling upgrades are the norm, where only a single node is ever down at a time.

At the beginning, we procured four initial nodes, which amounted to about 400 TiB of usable space. We now have just shy of 2 PiB of total installed capacity at each cluster. Our storage usage has grown quite a bit, moving from terabytes to petabytes, but I have no doubt that we will be able to continue growing at the same rate or even more in the future. The original Isilon had already been designed to scale to multiple petabytes, PowerScale will only continue to push that further. We highly value being able to grow our capacity without having to be concerned with platform limits.

PowerScale now also offers more choice when it comes to mixing and matching different types of storage nodes within the same cluster. For example, you can get all-SSD or NVMe nodes alongside old-fashion SAS disks, that you might want to consider adding when performance is critical in your environment. In our case, the performance we get without these new nodes is sufficient for our needs. The best part is that should we ever need to provide a faster pool of disks, there is no administration overhead to do so: just add the new node types, set the tiering rules that you want, and let the system rebalance itself. No partitioning, no moving data around yourself. It is transparent to the end-users as well as the administrators. You can even tier data to a cloud pool for the archive if you want! This simplicity is, again, one of the main reasons we decided to stay on the platform.

I needed technical support on a few occasions, specifically while implementing multi-protocol access for Linux and Windows clients. There was an instance when my engagement with support had to run for longer than I expected, but that was because the solution I wanted to achieve was highly complex from a technical perspective. We had to escalate the issue a few times to the next tier of engineers until they came through with a solution. It was always an excellent customer service experience, and I can certainly recommend Dell EMC Support to anyone who asks.

That said, we only tend to contact Support when we are unable to resolve issues or find the answers with need in the product knowledge bases, or the community forums. The availability of product information online is both comprehensive and of excellent quality.

The initial setup was straightforward. Since it was a green-fields implementation, we did not run into any issues. EMC, who later merged with Dell to form Dell EMC, even let us evaluate the platform in our own data-centre, so by the time we decided to procure the solution, all we had to do was to revert to “factory settings”. The longest part of the process was migrating around 84 TiB of data from our old data stores, as it happens with any data migration exercises. But once the data had been relocated, it became a matter of simply pointing the servers to the new data store entry points. Users were happy to take it from there, and were certainly overjoyed at the additional space they had to work with.

It was a long time ago now so details are fuzzy, but we dealt with EMC directly, with the help of an integrator for some of the initial design and implementation. EMC was our primary point of contact for platform-specific support when we first started, and their guidance around the different features of the platform was invaluable.

Today, that same integrator continues to help us with ongoing procurement, simplifying decisions around which of the many available node types might be the best suited to our environment, or ensuring that we stay on top of our node refresh cycle as older ones reach end of life.

Price was also a significant factor in our decision to go with PowerScale. The team at EMC, now Dell EMC, came through with a highly competitive offer that tipped the scales towards their solution. There was only one other solution around the same price point, but it could not match PowerScale on features. That other solution is no longer on the market.

The licensing model is interesting, because it is essentially “pay to unlock”. Most of the available features are software-defined, so they are already available in OneFS, the underlying Operating System, waiting for you to activate them as needed. There are a few additional costs, however. NDMP backups require you to install fibre cards, which are sold separately. Then of course you have the cost of tape and off-site storage, but you would have those same costs with most other platforms. Luckily, we do not need to back-up the whole cluster because we can rely on cluster replication and snapshots (on both source and target clusters) to achieve our RPOs. But we do have a legal requirement to preserve some data for an extended period, so we use tape for that.

We evaluated three other competing solutions based on multiple criteria. Some of those solutions no longer exist, or have evolved into a different offering. We went through a rigorous evaluation process, which assessed the platforms’ scalability, ease of use or complexity to administer, performance, and of course TCO. Isilon was the brand name that blew all others out of the water. It was an easy decision for us to make based on the criteria we set.

I give Dell EMC PowerScale a high 9 out of 10. It is not quite a 10, mainly because we do not have a use for all the features it provides, which you need to be aware of from a security point of view (eg: to ensure that they do not introduce unexpected risk). The ecosystem has also grown to be somewhat more complex in terms of the many different types of nodes that you can have. This gives you a lot of flexibility, but it does go slightly against the idea of simplicity that was so attractive initially.

I use the solution in my company for our customers who are from the media, and as per the vendor, I can say that the tool is scalable for data storage.

The most valuable feature of the solution is the unlimited scalability. The tool has high availability and high storage capacity. The tool also offers flexibility in connection.

My company uses the tool's basic features, and some of our organization's customers moved to the product after seeing its functionalities. Our customers only use the scalability offered by the product for storage purposes, along with whatever the vendor provides as an extension for the tool.

As the product is used for basic purposes, there are not many areas in the tool that require improvement. The product is just fine for now. My company does not use many of the features of the product. I can tell what my customers want to improve in the product, and I believe that they don't want anything to be changed in the solution.

The support offered by the product is an area of concern where improvements are required. My customers don't receive much support. The support has slowed down a bit. For Vietnam, the support has to be worked on since it is slow in our country.

I have been using Dell PowerScale (Isilon) for three years. My company has a partnership with Dell.

It is a stable solution. We don't have issues so much with the stability part. Stability-wise, I rate the solution a nine out of ten.

Scalability-wise, I rate the solution a ten out of ten.

My company's customers are from the media involved in games and movies.

For scalability, there is just a need to connect to the right connections.

My company's clients are medium-sized businesses.

The solution's technical support team is slow in Vietnam. I rate the technical support a six out of ten.

Neutral

The product's initial setup phase is taken care of by the engineers from the product side, so my company does not have much experience in it. My company gets a deployment service from Dell, so we don't need to configure anything as everything is already configured. We just need the information for the configuration, though it is all completed for me.

The solution is deployed on the private cloud.

The solution can be deployed in a day.

The product cost is affordable. It was not very high and not too cheap.

Speaking about the integration part, just mapping the NIS server is enough. An NIS server can be integrated with the tool, making it possible to share parts with the client.

In the media, there is a need to switch files without connecting to the internet, so on the website, they don't use much of anything. Customers move the data to Dell PowerScale, especially the things they can't just use over the internet. We don't use AI for now.

The biggest benefits experienced by the users of the product revolve around the fact that the tool offers scalability.

I can recommend the tool to others.

If you have more data to store and need to scale up, then I recommend that you use Dell PowerScale (Isilon).

I rate the tool an eight out of ten.
