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.

Achieve cost-effectiveness with superior performance while needing to address cluster support
I am working with Microsoft Storage Spaces Direct for applications, SQL, and VRS. I am an integrator for this solution The price performance is the best advantage of Microsoft Storage Spaces Direct. They introduced the All-Flash array using SSD or NVMe drives without cache drives. It is…

Achieving seamless cost-saving implementation with exceptional support
The best features that StarWind Virtual SAN offers include the price because comparing to other virtual SAN solutions, this one is the best, and it also has a great support team behind it. My experience with their support has been positive, as their guides regarding the integration are very useful. They have some awesome guides online that show you exactly how to configure the product, how to do the initial setup, and you can speak with them directly. They will be able to connect and verify your setup, run its parameters and see exactly what's working and what is not, and they really help you with that. StarWind Virtual SAN has positively impacted my organization and my customer through initial cost saving. They use this product in a dark site, so I'm not able to provide any additional details about this, but they were really glad about it, they're still using it, and they asked for extending the capacity for it and the support. They really want to use it and are enjoying using it.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Using this solution has made our backups more reliable."
"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."
"The most valuable feature of this solution is performance."
"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 uses the same platform for connectivity so integration is seamless."
"The initial setup is pretty quick."
"It performs well and it is also very fast."
"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 initial setup is straightforward."
"The performance, reliability, and affordability has been most valuable."
"The most valuable feature are the caching capabilities using the storage class memory."
"The most valuable feature is that there is no single point of failure."
"Its technical support is excellent."
"The price performance is the best advantage of Microsoft Storage Spaces Direct."
"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."
"It's mainly about the storage expansion, like in hyper-converged solutions."
"The ability to choose our own hardware and our own vendors for this was hugely beneficial, as we had pre-existing relationships with vendors we wanted to maintain."
"Active-active HA provides top performance and redundancy."
"PowerShell library is pretty good feature as I created with APC PowerChute a script to put volumes on maintenance mode then turning off the StarWind nodes together with the VM and Hosts when UPS reaches 15 percent, this way after a blackout or electrical problems when turning servers on again, there is no issues for syncing or data loss due to energy interrupts."
"I like the asynchronous replication and failover features. They are what I'm primarily using it for. The asynchronous replication is helpful because our servers are backed up continuously throughout the day. If anything goes wrong we just fail over immediately. That is a very nice feature to have."
"A typical system administrator with minimal experience in Hyper-V, VMware, or Windows can do VSAN configuration and maintain VSAN operations."
"This product now allows us to migrate virtual machines between nodes as if we had a dedicated $100,000 SAN in the mix without the additional cost and management of the SAN."
"The performance of the solution is accurate and concise."
"The product's core feature of virtualizing our storage is by far the most valuable."
 

Cons

"I would like to see more monitoring capability included in the next release of this solution."
"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."
"Its configuration should be easier."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"The features provided for SMB customers are limited."
"Its configuration should be easier."
"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."
"The documentational aspect of FlashBlade needs improvement."
"There is a lot of room for improvement. I would like to have more tools to monitor the function and problems."
"Documentation management could be improved"
"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."
"I think the online documentation needs a lot of work and so do the sizing tools."
"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."
"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."
"It is difficult to get a hardware compatibility certification for the solution."
"Scalability should be further improved, especially considering the possibility that environments may grow exponentially."
"If there are domain controllers inside the cluster, there needs to be some sort of logic allowing them to boot independently so all the rest of the domain clients can gain the authority they need to come online."
"The console is something that I believe could be enhanced."
"The system performs as expected, but we're always looking for performance improvements regarding the best utilization of NVMe disks."
"More comprehensive reporting and educational resources for error resolution would enhance the user experience."
"I would like additional documentation regarding possible networking configurations with 10GbE switching."
"It took a bit of knowledge and support to put in place but once installed it works fine. Migration (HyperV) from one server to another sometimes takes longer than expected but there is no data loss even if the host crashes."
"I had to buy upgraded support, which was not a problem, but it wasn't a prorated amount, so I paid for the support, the full upgrade, but I only got a couple of months out of it because it was only good until renewal time."
 

Pricing and Cost Advice

"I understand that it is competitively priced compared to other brands."
"I feel that the price could always be lowered."
"The price is a little high."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"Licensing fees are paid yearly."
"We used a reseller for the purchase."
"The price could be cheaper."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"With the data center licensing and everything that is connected to that, this solution is relatively costly."
"Cost-wise the product is one of the more affordable within the category of products."
"The solution is expensive."
"The pricing is more than reasonable."
"The pricing is fine for the work that it does."
"We found that the pricing was perfect; simple and clear."
"StarWind is a low-cost, full-featured alternative to the traditional SAN environment, and their support will guide you every step of the setup."
"This is the best priced solution for an SMB."
"I think that purchasing StarWind Virtual SAN Professional Edition would be optimal for most."
"The cost takes into account the number of nodes, so the size of the storage is not important."
"This solution has a great price for the functionality."
