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 snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."

"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

"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 onboarding and integrated monitoring tools are pretty good."

"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

"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."

More Pure Storage FlashBlade pros

"The ability to have a feature-rich software set which extends the capabilities of the back-end storage arrays."

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

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

"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."

"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 can failover easily, because a lot of our data is replicated from family to the second replication."

More IBM Spectrum Virtualize pros

"The solution has provided our company with a fully redundant virtual environment at half the cost of a traditional SAN implementation."

"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 hardware footprint is great. We've got two 2U servers which replaced four 2U servers. Granted, they were about three years old at that point, but we actually increased our processing capacity by about 50 percent while keeping our storage capacity about the same. We've actually been able to downgrade to a half rack from a full rack because we've gotten rid of some of our network equipment and some of our additional storage arrays."

"Having this all backed up by pro-active support gives us good peace of mind."

"With proactive support, StarWind deploys and configures the solution for you."

"The full suite of redundancy gives a nice sense of security for the whole environment."

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

"Being able to upgrade machines and software during business operations just by switching nodes has been a huge improvement. We"

Cons

"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 features provided for SMB customers are limited."

"There could be improvements in public cloud integration."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

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

"I have not seen ROI."

More Pure Storage FlashBlade cons

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

"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."

"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 integration would be an option that we would like, but I understand that's not how it's going to be implemented."

"NBME support and support for a higher Fibre Channel lengths could be improved, but those are already on the roadmap."

"GUI should be developed in HTML5 as opposed to Java."

"The Storwize port is not so stable."

"The training program could be improved."

More IBM Spectrum Virtualize cons

"Although the setup documentation was very complete and succinct, I found StarWind documentation to be a bit sparse."

"Perhaps the initial configuration and documentation could be a little clearer and simpler to follow."

"The truth is that the operation and support offered is good, but we consider that the product's usability could improve, as well as the data resynchronization time after an unexpected closure."

"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."

"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."

"There is room for improvement in the setup and installation phase. We had massive problems connecting the StarWind appliances to our network infrastructure. That wasn't necessarily a StarWind problem. I don't know if their business partner in the UK wasn't used to having to deal with the supply of the cabling infrastructure, but that's where the problems started."

"I had some initial difficulties understanding the solution which could have been solved via additional documentation aimed at newcomers."

"We ran into some issues with going from Hyper-V 2012 R2 to Hyper-V 2019."

Pricing and Cost Advice

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

"The product is very expensive."

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

"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."

"Our licensing is renewed annually."

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

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

"Licensing fees are paid yearly."

More Pure Storage FlashBlade pricing and cost advice

"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."

"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."

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

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

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

"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."

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

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

"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."

"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."

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

"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."

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.
