High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

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 most valuable feature is Safe Mode."

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

"Using this solution has made our backups more reliable."

"It uses the same platform for connectivity so integration is seamless."

"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."

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

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

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

More Pure Storage FlashBlade pros

"The main positive impact that Microsoft Storage Spaces Direct has had on my company over the years is increasing performance; our checks show it is three times faster than VMware, making us extremely happy and motivated to keep using it."

"The price performance is the best advantage of Microsoft Storage Spaces Direct."

"The most valuable feature are the caching capabilities using the storage class memory."

"The flash ability, in terms of tiering and caching, is amazing"

"The performance, reliability, and affordability has been most valuable."

"The most valuable feature is that there is no single point of failure."

"It's mainly about the storage expansion, like in hyper-converged solutions."

"The initial setup is straightforward."

More Microsoft Storage Spaces Direct pros

"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."

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

"UI Options are simple and easy to find."

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

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

"The setup was easy to deploy, and management is simplified compared with traditional SAN solutions."

"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."

"The initial setup seems to be very straightforward."

Cons

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

"I would like to see better integration."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

"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."

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

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

"The documentational aspect of FlashBlade needs improvement."

More Pure Storage FlashBlade cons

"It is scalable, but only beyond two nodes. If I go for two nodes it's not scalable. I need to build a complete cluster from the beginning if I'm going for two nodes."

"The integration is not difficult because there is no GUI, but we need to use a PowerShell command. This makes it difficult to monitor and to see the components' statuses."

"More optimization could be done in terms of mirroring."

"Microsoft closed the shared cluster support, which is important for the solution."

"There is a lot of room for improvement. I would like to have more tools to monitor the function and problems."

"The management tool within this solution could be improved. We would also like to be able to access services like Azure when using this solution."

"I think the online documentation needs a lot of work and so do the sizing tools."

More Microsoft Storage Spaces Direct cons

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

"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."

"We were slightly disappointed with the hardware footprint. We were led to believe, and all the pre-sales tech information requirements pointed to the fact, that it was coming on Dell hardware. Then it came on bulk servers."

"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."

"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."

"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."

"It would be nice if it were possible to do the ISCSI setup that you do on Windows directly in the management GUI of StarWind."

Pricing and Cost Advice

"We used a reseller for the purchase."

"The price could be cheaper."

"The product is very expensive."

"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 pricing for FlashBlade is between cheap and moderate."

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

"Our customers have seen a reduction in TCO."

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

More Pure Storage FlashBlade pricing and cost advice

"With the data center licensing and everything that is connected to that, this solution is relatively costly."

"The solution is expensive."

"Cost-wise the product is one of the more affordable within the category of products."

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

"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."

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

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

"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."

"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."

"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."

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

Overview

FlashBlade is the industry’s most advanced scale-out storage for unstructured data, powered by a modern, massively parallel architecture to consolidate complex data silos (like backup appliances and data lakes) and accelerate tomorrow’s discoveries and insights.

Pure Storage

Storage Spaces Direct uses industry-standard servers with local-attached drives to create highly available, highly scalable software-defined storage at a fraction of the cost of traditional SAN or NAS arrays. Its converged or hyper-converged architecture radically simplifies procurement and deployment, while features like caching, storage tiers, and erasure coding, together with the latest hardware innovation like RDMA networking and NVMe drives, deliver unrivaled efficiency and performance.

Microsoft

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.
