Eric Black - PeerSpot reviewer
The ability to leverage multi-tenancy along with immutability is a huge benefit for us
The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.
Eric Burgueño - PeerSpot reviewer
Simplified data management, tremendously reducing our users’ cognitive overhead
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.
Steve Qualls - PeerSpot reviewer
Offers the ease with which you can move data between on-premises storage and the cloud and then retrieve it back on-premises when necessary
IBM Cloud Object Storage supports big data and analytics workflows. However, I usually have to refer to my documentation for that. Cloud environments are part of almost every project I've been involved in over the last few years, but I rely heavily on documentation whenever I need to do anything in the cloud. I know the basics, but the technical details always need refreshing. I create the drawings or diagrams of how the on-premises and cloud environments interact. So, visual representations are helpful. I'll diagram the on-premises environment, the cloud environment, and any appliances in between and then work from there. The integration capabilities simplified our data workflows. Like, the integration itself is pretty easy. The access appliances create the connection between both environments.

Quotes from Members

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

Pros

"The product is scalable and easy to expand."
"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."
"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."
"The onboarding and integrated monitoring tools are pretty good."
"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."
"We have seen a reduction in the total cost of ownership by around 20%."
"The most valuable feature is Safe Mode."
"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."
"The most valuable feature is its single space of storage."
"The most valuable features of the solution are flexibility and ease of implementation."
"PowerScale has made it extremely easy to scale file data across our organization. We have two implementations of Isilon. One is a replica of the other. When scaling, we add nodes to each location and expand the cluster. The process is straightforward."
"The solution has simplified management by consolidating our workloads. Rather than managing all the different workloads on different storage arrays, Windows Servers, etc., we just have one place per data centre where we manage all their unstructured data, saving us time."
"The solution is stable."
"We use the solution internally to support our own managed servers and run our own support center."
"The tool comes with cheap disks and works fast for video content."
"The tool's most valuable features are scalability and stability."
"The standout feature of IBM Cloud Object Storage is its top-notch security, making it ideal for sensitive applications like mobile financial transactions."
"Overall, I rate IBM Cloud Object Storage a ten out of ten."
"IBM has the most number of additional services, this is the main advantage."
"IBM Cloud Object Storage integrates well."
"One of Cloud Object Storage's best features is infinite capacity. This is one of the main advantages if you don't want to use your own storage. You also have the ability to write only, write once, and read many. It's like tape storage but software-based. This feature is essential for financial institutions that require that kind of protection if you write backup or data there."
"The capability to replicate data in different locations is valuable since it enables customers to have a cluster over various sites."
"The integration itself is pretty easy. The access appliances create the connection between both environments."
"The most valuable feature I like is when you connect it via CLI plug-in...It is a stable solution."
 

Cons

"The features provided for SMB customers are limited."
"I would like to see better integration."
"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."
"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."
"I would like to see more deduplication."
"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."
"It would be good to have synchronized mirroring between two clusters without using a third-party program."
"Isilon has limitations on the number of files that can be generated."
"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them. We had old hard drives with moving parts in Dell PowerScale, and due to this, we must switch to a more efficient environment with all-flash."
"Dell PowerScale (Isilon) is a bit expensive compared to other products."
"We lost our technical sales reps about two years ago. We haven't gotten one assigned to us and we'd love to have one."
"The analytics could be improved."
"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[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."
"Some improvements to the NFS support would be of interest to us."
"IBM Cloud storage is not cheap, but it could be."
"The performance could improve in IBM Cloud Object Storage. The throughput or objects per second can have degradation."
"IBM has limited cloud storage."
"Sometimes technical support lacks a comprehensive understanding of the entire solution, only focusing on the product they support."
"If I had to choose one area, it would be making the consoles more intuitive would be helpful. Sometimes, they can be a little complicated if you're not familiar with them."
"One area where IBM Cloud Object Storage could potentially improve is in modernizing its underlying codebase."
"One improvement could be incorporating a feature similar to Dropbox's version history. This would allow users to track modifications made to files over time, which is particularly important for maintaining a record of changes. While the free version might not include this feature, it could be included in the paid version to provide added value to clients. Additionally, having a version history feature that allows users to access modifications made to files over the past three months could be beneficial."
"The performance could be better. It isn't bad, but everything is network-based, so you have a performance penalty on the network. You can never achieve the same performance as hardware. That's the disadvantage of cloud storage solutions in general. Cloud performance is one of the main issues clients have."
 

Pricing and Cost Advice

"Our customers have seen a reduction in TCO."
"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."
"I feel that the price could always be lowered."
"The product is very expensive."
"Our licensing is renewed annually."
"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."
"The price of this solution could be made more affordable."
"The pricing for FlashBlade is between cheap and moderate."
"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"It is a really expensive solution."
"The general cost for a system like this is expensive. The total cost depends on your use case. You need to pay for every additional feature that you use."
"I always want things to be less expensive. However, I would say the pricing is fair. Their costs are in alignment with their competitors. It is a good value for the money."
"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."
"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."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"You have the option of a monthly or yearly license. Most customers choose the monthly option. I understand what you would like to say. IBM also lets you choose among four types of Cloud Object Storage. The difference is usage, performance, etc. Of course, high-performance storage is more expensive, while low-performance storage is for cold data, and it's really cheap."
"Like most cloud providers, IBM likely charges based on storage capacity, typically per gigabyte or terabyte. Their pricing is competitive when compared to AWS or Microsoft."
"Pricing is not cheap."
"IBM Cloud is cheaper than AWS. If you want to scale your cloud infrastructure, it can be bought at almost the same price."
