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.

Proactive support with improved speed and resilience

There was a long delay with shipping, which we weren't expecting, but we were kept updated throughout. It wasn't made clear to us that we needed to provide our own SFP modules to connect to our infrastructure, so that could have been a bit clearer. It would be amazing if there was, perhaps, a more automated process for updating the hosts themselves, although the maintenance mode works well. Our StarWind command center doesn't seem to have all the options available currently, which support is investigating for us.

Quotes from Members

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

Pros

"The solution provides many controllers."

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."

"Pure Storage FlashBlade's scalability is one of the most valuable features, and importantly, it always works, allowing for seamless upgrades."

"FlashBlade offers low latency, high throughput, and seamless scalability."

"The tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."

"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

"It performs well and it is also very fast."

"The initial setup is pretty easy and simple."

More Pure Storage FlashBlade pros

"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."

"It provides transparency, because of its advanced copy features."

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

"It has the ability to seamlessly move hardware in and out as we refresh technology."

"Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places."

"The scalability is very good. It can handle anywhere from very small to large enterprise class."

"The SVC gives excellent performance with tiered storage behind it."

More IBM Spectrum Virtualize pros

"Reliability and overall uptime are key as we're also hosting client environments in addition to our own."

"Customer service has been excellent. Any questions we have had have been answered quickly."

"Overall, the solution has improved our system's performance. I was concerned about the physical-to-virtual conversion of our database server. It's actually much faster now, as a virtualized host on this Hyper-V cluster."

"The presence of built-in storage saved the company from having to purchase a separate storage array and related network equipment."

"The high-quality hardware options, directly affecting performance, have significantly improved the user experience and are well worth the cost."

"This solution came preconfigured. All we needed to do was plug it in and move our VMs."

"The easy way everything can be configured and ready to run in less than a day is great."

"What makes it valuable is the high-availability. In the education field, when you've got students in classrooms, any loss of service disrupts the lessons to a point that the whole lesson is affected. For part of the business which isn't business-critical, to have a little bit of a hiccup wouldn't be such a big thing, but here, it's the high availability of service that is important."

Cons

"There could be improvements in public cloud integration."

"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."

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."

"The documentational aspect of FlashBlade needs improvement."

"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."

"The solution is expensive."

"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."

"They need better integration with public clouds along with a better hybrid solution."

More Pure Storage FlashBlade cons

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

"The case logging process is efficient, but resolving software problems takes too much time."

"t is limited in terms of a single system to eight nodes or four, what they call IO groups."

"There are things that occur when you get to this size and capacity. We're very large, i.e., petabytes. When you get to that sheer volume of the numbers of things, it is too big for people to keep track of."

"Level 1 technical support needs improvement."

"For improvement considerations, I would probably say multiple sites."

"The Storwize port is not so stable."

"In general, the migration is complicated. Though, it is case-by-case."

More IBM Spectrum Virtualize cons

"We'd like an easier setup for Windows updates on the Hyper-V servers so you don't have to use a script to ensure auto-updating is done."

"The StarWind Command Center web portal could use some work."

"The only issue we have had was the issue of performance, however, that is only due to the fact that we purchased a mix of SSD and regular spindle drives, and restoring databases was slow as it was trying to restore the database using the spindle drives."

"In the future, it would be nice to be able to migrate from the Windows vSAN to the Linux vSAN without having to do a full restore from backups."

"The only issues are when Hyper V itself has limitations and I'd love to see support or enhancement in the area of direct-attached GPU cards."

"At the moment, the initial configuration is very technical and error-prone. That is the reason Starwind does it for you as a service, which is a great thing. But it would be nice if we could change or rearrange storage assignments ourselves."

"Most meetings are done via Zoom, and I'm sure you could switch to a text based conversation if needed as they seem like a very accommodating team. It's not something I would worry about if you are a potential client."

"CSVs require the storage to be configured through iSCSI, even though the storage is local."

Pricing and Cost Advice

"Our licensing is renewed annually."

"The price of this solution could be made more affordable."

"I understand that it is competitively priced compared to other brands."

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

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

"The price could be cheaper."

"The product is very expensive."

"The price is a little high."

More Pure Storage FlashBlade pricing and cost advice

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

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

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

"The entry point of pricing for this product is the most amazing price ever in the industry."

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

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

More IBM Spectrum Virtualize pricing and cost advice

"We looked at Nutanix and found it did almost the same thing but for more money. In fact, StarWind was nearly one-third of the price; it cost us £36,000. That includes five years of monitoring... The Nutanix was near enough £110,000 for relatively the same amount of performance and storage."

"In terms of cost, a storage array is more expensive... For half the cost of Compellent, I got two hosts, more storage, and redundancy."

"Its cost was reasonable."

"Our entire package was around $35,000 for everything, including three years of support."

"I honestly feel that there's no one else in the market doing what they're doing for the price point that they're doing it at. That's why I asked them about investing in their company. I think that the options they're providing and the software that they have is sort of revolutionary for the price point... The total cost was $24,400."

"This was all completed at an affordable price point for an SMB, which was also a key element for an NPO."

"We didn't have any issue with pricing or any of the sales process."

"The HCA price is all-inclusive (setup, hardware, support, warranty), except for your standard Microsoft Server licensing."
