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.

Offers good features like Fusion and stable product with better customer service
Fusion is the only best feature, but it's a very good feature. Nexenta is a very old product. Nexenta is a well-established product used in the UK, US, India, Dubai, Qatar, and other countries. It is very good. The interface is up to date. Everything is up to date. The OS version was recently upgraded to 5.5 FP3. AI features: DataDirect Networks owns Nexenta and has won awards for AI. They continuously work on AI features. DDN also has a product called Tintri Infinia with AI features. And NVIDIA product also has AI features. I look forward to working on those products.

Quotes from Members

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

Pros

"The initial setup is pretty quick."
"It performs well and it is also very fast."
"The most valuable features are the Metro clustering, and disaster recovery."
"The main feature I have found to be product replication."
"Using this solution has made our backups more reliable."
"It uses the same platform for connectivity so integration is seamless."
"It's very easy-to-use."
"The product is scalable and easy to expand."
"The ability to have a feature-rich software set which extends the capabilities of the back-end storage arrays."
"The scalability is very good. It can handle anywhere from very small to large enterprise class."
"The most valuable feature is its reliability."
"There are many benefits to this solution. Storage virtualization and the ability to migrate massive amounts of data to other systems without impacting your client are the most valuable. It is non-disruptive for my users. We migrated 350 terabytes of data in one night to a new machine without a small system going down and a single user complaining about the performance. You have to fine-tune a lot of storage machines constantly for performance and for making sure that they are optimal, but IBM Spectrum Virtualize does this by itself. It does the adjustment on its own, and it does it right. That's what makes it different. I had a huge VSP from Hitachi, which is also a type of virtualization-based engine but with a decent size. It was a continuous performance-tuning exercise. I never had that issue with IBM Spectrum Virtualize."
"Although the GUI from the XIV was used (in my view), IBM has polished and refined the GUI providing a pleasant and easy to navigate GUI experience."
"We acquire companies (and things), so we end up with odd hardware. We bring it behind the SVC and it allows us to migrate stuff off of it seamlessly. SVC can also cover up a host of defects of the underlying storage."
"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."
"The SVC gives excellent performance with tiered storage behind it."
"It has a feature called Fusion that makes it more secure and productive."
 

Cons

"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."
"There could be improvements in public cloud integration."
"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."
"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 nice if you could store file-based in the same box with the same technology."
"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."
"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."
"I would like to see more VM-Aware features in the next release of this solution."
"In general, the migration is complicated. Though, it is case-by-case."
"GUI should be developed in HTML5 as opposed to Java."
"Tighter integration with cloud storage might be useful as a target for a variety of use cases."
"The disk reliability is not that good."
"t is limited in terms of a single system to eight nodes or four, what they call IO groups."
"There are big arrays now, and if a customer wants add more disks to it, you have to have another array. Adding disks to existing arrays is one of the most demanded things from our customers."
"The training program could be improved."
"The integration would be an option that we would like, but I understand that's not how it's going to be implemented."
"There were some SMB issues, but they were resolved."
 

Pricing and Cost Advice

"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."
"The price is a little high."
"The price of this solution could be made more affordable."
"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."
"We used a reseller for the purchase."
"I rate the tool's pricing a seven to eight out of ten."
"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."
"Licensing fees are paid yearly."
"It has a lot of advanced functions for a reasonable price."
"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."
"I think it is a good value for the price."
"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."
"This solution came as an additional cost for the TSM package we chose."
"We would like the CPU cycle to save more on the licensing costs for us."
"The entry point of pricing for this product is the most amazing price ever in the industry."
"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."
