Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

Unified file sharing has simplified multi-tenant access and has delivered seamless data replication
Dell PowerScale (Isilon) includes its replication features; when we decommissioned our old Isilon cluster, we migrated all of the data to a new cluster, and it was pretty seamless. All you have to do is create the certificates and make those certificates available to the target cluster, then initiate a few jobs. The inter-cluster replication feature, called SyncIQ, allows you to set up all of the jobs and move your data entirely, either timely or all at once. Another suitable feature is the ability to back up your directories; you can take snapshots for all of your directories, and in fact, I believe you can take around a thousand snapshots for a single directory. The inter-replication, geo-replication is one feature. Dell provides a variety class of hardware suitable for your workloads, meaning if your data is just lab and not critical, you don't have to spend much on the hardware; conversely, if your data is mission-critical, you can buy a high-performance node from Dell. Additionally, you can span Dell PowerScale (Isilon) cluster to a large number of nodes, and code upgrades are pretty smooth because all protocols will be upgraded under a single piece of code. Since it provides a single file system that spans across the nodes, you don't have to worry about that directory structure being separately created on individual nodes, making it a fitting solution for a data lake solution because you can access the same data from multiple protocols.

Offers reliable performance and availability for large deployments
I would like to see improvements in Red Hat Ceph Storage not because I necessarily think it needs improvement, but because I generally prefer to do things manually rather than following the containerization part. Current deployments are based on containers, but I deploy manually with my scripts and controls. If there are no Kubernetes-like requirements, I often prefer to deploy a whole manual process. I don't ask for improvements in the deployment model because Red Hat has its own philosophy about making things, but it's my personal choice that I prefer things manually. Some features are available only in the containerization part, so if those are also available in manual deployment, that will help.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution is very reliable."
"The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."
"Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"After switching to Everpure FlashArray, we saw significant results, as whatever hardware we used before is now compressed to 80%, maximizing space utilization in a single system."
"The most valuable features are the replication of data and the continuous snapshot that we can take from the disc."
"The most valuable feature is its speed."
"It saved a lot of space, as far as physical space in our data center."
"I would recommend Pure Storage, as it is well-established."
"This has really changed the way our company can acquire and process data in the field, allowing us to differentiate ourselves against all our competitors."
"The features of Dell PowerScale that I appreciate most are the expandability, which allows me to establish a foundational baseline and then add capacity as needed."
"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."
"Overall, the hardware itself, and the OneFS file system, are the best selling points, combined with the delivery and the installation."
"The reliability and stability of Dell PowerScale (Isilon) is good, with no downtime."
"Dell PowerScale has positively impacted my organization as the students and the teachers are much happier using our services."
"Customer service is absolutely satisfying, rating at least nine out of ten, as they have managed previous issues well."
"Isilon is flexible in supporting various data workloads while keeping them protected. Dell continues to release updates and patches which enhance the use of this solution. This includes offering ransomware protection."
"I can compare Red Hat Ceph Storage with products from other vendors; I explored quite a few, but I still find that Red Hat Ceph Storage is making the most disruption."
"We have not encountered any stability issues for the product."
"The ability to provide block storage and object storage from the same storage cluster is very valuable for us."
"Ceph was chosen to maintain exact performance and capacity characteristics for customer cloud."
"Red Hat Ceph Storage is working exactly as it should be; it's running in the background, it's working, and it doesn't bother me."
"Stratus allows more reliability than all the other types of computers available."
"Most of the features are beneficial and one does not stand out above the rest."
"I like the distributed and self-healing nature of the product."
 

Cons

"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"It is a bit expensive."
"The price of this solution could be improved."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"I would like a feature to integrate with external or cloud solutions."
"We have not seen a reduction in our TCO nor have we seen ROI."
"From the disadvantages perspective, if I need to replace a drive, I must shut down that node."
"We have had issues with internal load balancing between some of the shelves. That is an ongoing issue that support is trying to address."
"An example of something that is problematic at the moment or that I would want to see improved is that there needs to be further delineation between access zones and settings."
"We used to have a chat feature available on the support site. It's not available to us anymore."
"Dell PowerScale (Isilon) certainly has room for improvement; since it does not provide SAN at the moment, I would look for Dell to create a complete unified solution just like NetApp."
"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."
"I'd like to see more Iceland products in the cloud so that we can port our data into different environments if needed. I would also like to see a virtual appliance or software-defined Iceland product."
"Dell PowerScale could be improved by simplifying management and monitoring, making AI analytics integration more seamless, and reducing the complexity and cost of scaling."
"Areas of Red Hat Ceph Storage that have room for improvement include more promotion. Many people do not know about the Stratus case, which is one of the most reliable systems available in the world, but they are not aware that a system can keep working even if there is a hardware failure."
"What could be improved in Red Hat Ceph Storage is its user interface or GUI."
"The licensing cost is excessively high. This is a significant issue from my perspective."
"If you use for any other solution like other Kubernetes solutions, it's not very suitable."
"Ceph is not a mature product at this time. Guides are misleading and incomplete. You will meet all kind of bugs and errors trying to install the system for the first time. It requires very experienced personnel to support and keep the system in working condition, and install all necessary packets."
"It needs a better UI for easier installation and management."
"Please create a failback solution for OpenStack replication and maybe QoS to allow guaranteed IOPS."
"Ceph Storage lacks RDMA support for inter-OSD communication. That is a huge loss in terms of performance."
 

Pricing and Cost Advice

"It is light years beyond anything else with the same price point."
"It is a more expensive solution, but it is worth it. You are getting what you paid for."
"There are no fees for licensing. The hardware is paid for only once."
"The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."
"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."
"I would rate it a seven out of ten for pricing. It could be improved."
"The price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"We use the TNA approach which is a great opportunity for us to better manage the licenses based on how much consumption is available for the different customers so we can use that approach and scalability."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"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 only drawback for us is that it's a large upfront investment. This was a huge decision for a startup company to make. It took a bit for us to get over the line on it, but we have not regretted it."
"Dell PowerScale (Isilon) is an expensive solution."
"It is an expensive solution."
"Dell PowerScale is expensive on the start-up side but we can recoup those costs quickly by not having to reapply the savings to other equipment."
"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"We never used the paid support."
"The operational overhead is higher compared to Azure because we own the hardware."
"The other big advantage is that Ceph is free software. Compared to traditional SAN based storage, it is very economical."
"If you can afford a product like Red Hat Ceph Storage then go for it. If you cannot, then you need to test Ceph and get your hands dirty."
"Most of time, you can get Ceph with the OpenStack solution in a subscription​​ as a bundle.​"
"There is no cost for software."
"The price of Red Hat Ceph Storage is reasonable."
"I rate the product’s pricing an eight out of ten."
