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.

Built-in compression enhances data management efficiency

I have noticed that the technical support for software issues, such as with Spectrum Protect, needs improvement. The case logging process is efficient, but resolving software problems takes too much time. This delay can hinder customers and strain vendor relationships. For hardware issues, IBM handles them efficiently, but software-related support requires enhancement. Overall improvement in support for software cases is necessary.

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 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's very easy-to-use."

"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."

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

"The most valuable features are the Metro clustering, and disaster recovery."

"Speed and ease of use are the two most valuable features."

More Pure Storage FlashBlade pros

"Migration from configurations where servers have storage provisioned from older SAN disk systems to newer storage systems is almost seamless using image mode migration techniques, with only a short outage of the servers."

"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."

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

"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 ability to add the virtual machine on the Spectrum environment to sort out the data movers(DMs) and their schedules is a valuable feature. You are able to have, for example, four data movers to balance them so you do not have too much work on one data mover."

"The biggest benefits of IBM Spectrum Virtualize are its stability, data security, and customer support."

"I like that it can virtualize more than three hundred storage providers."

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

More IBM Spectrum Virtualize pros

"It improved all services running on the new cluster and took up less space and less energy."

"The solution has easily deployed instances for multiple fast-paced projects."

"The low cost of this solution has also made a big difference in our budget, which has been very helpful."

"We have found the live migration to be the most valuable feature. It allows us to seamlessly maintain our servers, as well as have peace of mind if something goes wrong."

"The StarWind command centre is a very handy tool to have. It allows less skilled staff to have a view and manage our virtual machines."

"We also substantially reduced network complexity by eliminating that standalone SAN. That reduced complexity has allowed us to concentrate on improving other areas of our network."

"Repair efforts have been reduced to nearly nothing."

"We no longer need multiple staff members performing small, mundane tasks."

Cons

"I would like to see more VM-Aware features in the next release of this solution."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

"Its configuration should be easier."

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

"Pure Storage FlashBlade should improve on more cloud integration."

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

"The documentational aspect of FlashBlade needs improvement."

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

More Pure Storage FlashBlade cons

"Tighter integration with cloud storage might be useful as a target for a variety of use cases."

"I hate I/O groups. If you start swapping I/O groups, they can be potentially risky. If they could get rid of the whole I/O group principle, the risk is not there anymore. I understand the fundamental thing about I/O groups, but they are risky."

"The Storwize port is not so stable."

"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."

"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."

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

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

More IBM Spectrum Virtualize cons

"Not much can be improved, to be honest."

"It would be amazing if there was, perhaps, a more automated process for updating the hosts themselves, although the maintenance mode works well."

"One area for improvement of the solution is that I had to get Windows, which I really didn't want because of the extra maintenance or overhead, as well as viruses, etc. It's going to take time for them to get their Linux to that point. They already have Linux but it's not as mature and they don't really support it on HCAs. They have it for individuals who want to use it on their servers, but not on HCAs."

"Over the past three years, there were two instances where our cluster had an issue, yet StarWind proactively notified me of those issues and effortlessly guided me through the process of correcting the issue with minimal effort on my part."

"I think some performance metrics would be nice to see, especially on the storage side."

"The only real flaw that I have seen so far is this hard drive that was accidentally ejected because when it was received and added back into the RAID. There was an error there. It was not added back into the RAID correctly, so I have an outstanding hard disk. Apparently, a guy just knocked it with his hand as he was in my office, so it was just a small eject. He said that he didn't crash into anything. That is the only thing that has reared its head."

"The only thing that can use improvement is the StarWind Management Console and Command Center."

"An emphasis on security can be improved."

Pricing and Cost Advice

"Licensing fees are paid yearly."

"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 product is very expensive."

"I rate the tool's pricing a seven to eight out of ten."

"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."

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"The price could be cheaper."

More Pure Storage FlashBlade pricing and cost advice

"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."

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

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

"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."

"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."

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."

"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."

"A desired feature or service would be the ability to have a hardware subscription plan that ensures routine hardware updates in conjunction with hyper-converged software."

"The other solutions we were looking at were priced much higher than this and they didn't necessarily have full redundancy... Nutanix and VxRail were in the final running... but it came down to our price point."

"The Nutanix piece was about $45,000, getting close to $50,000 with all the licensing involved, whereas the StarWind was less than half of that, after Microsoft licensing and such."

"When I researched they came the most cost-effective."

Pure Storage

IBM Spectrum Virtualize is a dependable solution that improves data value, security, and simplicity for new and existing storage infrastructure. Proven over 12 years in thousands of deployments, its innovative virtualization capabilities help organizations achieve better data economics by supporting new workloads that are critical to their success. IBM Spectrum Virtualize software helps make new and existing storage more effective and standardizes functions traditionally deployed separately in disk systems for greater flexibility and potentially lower costs.

IBM

For SMB, ROBO and Enterprises, who look to bring in quick deployment and operation simplicity to virtualization workloads and reduce related expenses, our solution is StarWind HyperConverged Appliance (HCA). It unifies commodity servers, disks and flash, hypervisor of choice, StarWind Virtual SAN, Microsoft Storage Spaces Direct or VMware Virtual SAN and associated software into a single manageable layer. The HCA supports scale-up by adding disks and flash, and scale-out by adding extra nodes.

StarWind HyperConverged Appliance consists of StarWind Virtual SAN, Microsoft Storage Spaces Direct or VMware Virtual SAN “Ready Nodes”, targeting those, who are building their virtualization infrastructure from scratch. In case there is an existing set of servers, we offer a “software only version”, which is essentially our years proven StarWind Virtual SAN. Basically, it’s the fuel powering StarWind HCA.
