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.

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 main feature I have found to be product replication."

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

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"The solution provides many controllers."

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

"The initial setup is pretty easy and simple."

"It's very easy-to-use."

More Pure Storage FlashBlade pros

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

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

"The initial setup is straightforward."

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

"Its technical support is excellent."

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

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

More Microsoft Storage Spaces Direct pros

"Their service is top-notch and if a node goes down they immediately are following up with us to make sure that everything is working smoothly."

"The redundancy of two identical nodes that can run alone allows us to have truly "no single point of failure" in our computing and primary storage infrastructure."

"High-availability is what I bought it for."

"The sales process is easy."

"The customer service has been the most valuable feature of the product to me."

"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."

"How quickly the StarWind solution replicates also gives us the confidence to know that in the event of catastrophic failure of any piece of hardware, we won't be far behind before things went wrong."

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

Cons

"I have not seen ROI."

"There could be improvements in public cloud integration."

"The feature that we're waiting on is better integration with the cell services."

"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."

"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."

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

"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."

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

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."

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

"On a scale of one to ten, I would rate the customer service and technical support of Microsoft Storage Spaces Direct a three, as there were issues that the Microsoft team could not pinpoint, leading to delays in finding solutions."

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

"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."

"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."

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

"Documentation management could be improved"

More Microsoft Storage Spaces Direct cons

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

"I'd like a better UI and some limitations on "breaking it.""

"It would be nice to have some kind of GUI interface implemented to give you an overall view of the system's health at a glance."

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

"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."

"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."

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

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

Pricing and Cost Advice

"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."

"We used a reseller for the purchase."

"The product is very expensive."

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

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

More Pure Storage FlashBlade pricing and cost advice

"The solution is expensive."

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

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

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

"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."

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

"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 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."

"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."

"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."

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.
