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 onboarding and integrated monitoring tools are pretty good."

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

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

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

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

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

"The performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

More Pure Storage FlashBlade pros

"IBM provides exceptional technical support, which I rate as the best along with Cisco."

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

"The abstraction flair and the abstraction layer. We had a mixture of different storage arrays, and the wonderful thing about SVC is is that it normalizes all it into a single driver. A single view that all hosts see simultaneously."

"The ease of management, the simplicity of the CLI, the speed of that interface, and the well-architected design of the product in general are valuable features."

"It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."

"In my opinion, the quick restore, the low latency, and the ease of use are some of the most valuable 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."

"It lowers cost. It does so by getting more efficient use out of the technology behind it."

More IBM Spectrum Virtualize pros

"StarWind's proactive support is my favorite feature."

"Being able to log on to the GUI to see specific data and usage statistics, executing clones, starting and stopping VMs, etc., is great."

"UI Options are simple and easy to find."

"We have the ProActive Premium Support and it has reduced our monitoring efforts. It has been very useful. They have been able to detect things such as when there's an issue with the cluster or they're getting some kind of weird reading that I have no idea about. They're really quick to let me know about it and even set up a schedule to address it. I've been very happy with their level of support on that."

"The option to deploy a hyper-converged system without an expensive storage switch was a benefit."

"StarWind is very resilient and built off of quality vendor hardware."

"The initial setup seems to be very straightforward."

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

More StarWind HyperConverged Appliance pros

Cons

"There could be improvements in public cloud integration."

"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."

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

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."

"The solution is expensive."

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

"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 the licensing fees improved as well as the price per terabytes."

More Pure Storage FlashBlade cons

"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."

"IBM could improve IBM Spectrum Virtualize by bundling Storage Scale and Storage Virtualize into a single appliance. This would provide a more appealing and cost-effective solution."

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

"The disk reliability is not that good."

"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."

"I would like to see them provide a unified platform that offers block, file, and object-based protocol access."

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

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

More IBM Spectrum Virtualize cons

"A possible thing is perhaps a customer portal to schedule a time with support online via a calendar."

"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 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."

"Product shipments did have a few bumps along the way, but that's to be expected when using any shipping company."

"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."

"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."

"I think that the pre-installation questionnaire was a little confusing and ambiguous."

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."

"Licensing fees are paid yearly."

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

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

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

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

"The pricing for FlashBlade is between cheap and moderate."

"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 Pure Storage FlashBlade pricing and cost advice

"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."

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

"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."

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

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

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

"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."

More IBM Spectrum Virtualize pricing and cost advice

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

"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."

"There is a bit of a start-up cost. Having never used HCAs before, I was reluctant to buy it. I would suggest that you jump in and do it, as I wish I hadn't wasted so much time."

"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."

"I was able to bring the price per year down by going out to a five-year plan."

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

"It's an all in one package, making it very easy."

"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."
