Has handled backup storage needs reliably and supports seamless upgrades

In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

Unified storage solution supports cross-vendor replication and diverse industries

One of the most valuable features of IBM Spectrum Virtualize is its virtualization capability. It allows for the creation of stretched clusters, which are crucial for running Linux-based workloads that need mirroring for boot disks. The solution also provides asynchronous and synchronous replication, supporting operations across different data centers. Its deployment options across public, private, and hybrid clouds add to its versatility.

Meets our customers' needs but they should move towards high-level scaling

I the product already has scalability features, but in terms of size maybe they could do more to work with parent storage and move to high-level scaling. That area, I feel, is a place where there could be some more options in this solution. It would be a way to improve the scalability in another direction, maybe options to scale out rather than just up. So far we have done very few installations. So maybe in the coming days, weeks and months, we would be able to come up with some additional features that are needed, but right now the product has the competitive features that our clients need.

Quotes from Members

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

Pros

"If you need high throughput the FlashBlade is the best solution for you."

"We can capacity plan at a greater level than we used to."

"I love this solution."

"I would recommend this solution to other interested companies because it's extremely fast."

"The most valuable feature of this solution is performance."

"It improves our organization by making the management much easier to access and not as time consuming, and it has made the management easy and simple."

"The initial setup is pretty easy and simple."

"The main feature I have found to be product replication."

More Everpure FlashBlade pros

"It makes data migration straightforward, and on the customer side, there is downtime, but it is very minimal."

"Being able to move things around from one array to the other has been the biggest feature for us."

"So when I say our storage services to our client were provided continuously - non-stop - for 12 months, it means that all customer servers had 100% uninterrupted, online SAN access to their data 24x7x365 (minus the power down)."

"It is a single pane of glass management interface, so once the storage is allocated to SVC, they only have one place to go to manage it for everything."

"I like all the features, but the most impressive recently has been the introduction of IBM's Flash Core Modules. They are a form of a flash drive, but they have many more features."

"We have all the tools in one place."

"The most valuable feature for sure is the abstraction of the storage."

"We are happy with the support that IBM provides us."

More IBM Spectrum Virtualize pros

"Compared to other products in this category that are competing with Dell EMC, Dell seems to us to always come out on top."

"Automatic rebalancing is the feature saving administration time, and also auto rebuilding."

"Comparing other products that are competing with Dell EMC (Enhanced Memory Controller), Dell seems to us to always come out on the high-side."

"They know how to clearly present any important data, including data flow and each drive's IOPS/bandwidth; and allow the user to easily monitor bottlenecks and problems"

"We are using it as the primary virtualization storage (both for internal corporate users and external customers) for VMware and Hyper-V virtualization platforms."

"The ScaleIO UI: EMC has been working with storage for a long time; therefore, they know how to clearly present any important data, including data flow and each drive's IOPS/bandwidth, and allow the user to easily monitor bottlenecks and problems, especially the rebuild and rebalance status of child objects."

"Automatic rebalancing is the feature saving administration time."

Cons

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"Compared to, for example, Hitachi NAS, the solution is not mature at all; it's just in its infancy as far as technology goes."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"I want efficiency. FlashBlade doesn't have efficiency now."

"I have not seen ROI."

"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."

More Everpure FlashBlade cons

"There are a few little GUI issues and stuff like that, but nothing major."

"Adding features for data deduplication is one area of improvement."

"The only errors I find sometimes is the solution tells me I cannot operate it because a service has turned off, you can just go back to the VM, go to services, and turn back the services. However, this should improve."

"Technical support at IBM is actually not as great as it used to be. It seems like IBM has decreased the number of people who can support this environment."

"The Storwize port is not so stable."

"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."

"We are not happy with the technical support. In the last seven or eight years, I honestly think that IBM's technical support has gotten way worse."

More IBM Spectrum Virtualize cons

"If they could introduce a write cache feature, the product would be perfect overall."

"There is room for improvement in the area of horizontal scaling."

"Ecosystem around the product: There is no built-in system for viewing history data, such as volume IOPS."

"It would be nice to set minimum IOPS per volume, besides just the maximum, to be able to satisfy this demand from customers out-of-the-box, not by calculating number of disks, etc."

"Ecosystem around the product: There is no built-in system for viewing history data, such as volume IOPS. We have to provide graphing by Prometheus and Grafana, which would be a good new feature in ScaleIO."

"I think ScaleIO already has some features for scalability as it is part of the reason for the product, but in terms of size, maybe they should try to address parent storage."

Pricing and Cost Advice

"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 pricing for FlashBlade is between cheap and moderate."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"Our licensing is renewed annually."

"I feel that the price could always be lowered."

"The price could be cheaper."

"Our customers have seen a reduction in TCO."

"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."

More Everpure FlashBlade pricing and cost advice

"Do a proof of concept, if you are not comfortable jumping in, but do it."

"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."

"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."

"It has a lot of advanced functions for a reasonable price."

"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."

"We would like the CPU cycle to save more on the licensing costs for us."

"This solution came as an additional cost for the TSM package we chose."

"I think it is a good value for the price."
