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.

Jccerong Heron

System Engineer at a tech vendor with 10,001+ employees

Support team has guided us through deploying virtual storage on legacy hardware and reducing operational costs

The reason I chose StarWind Virtual SAN for this particular scenario is really the features, the ease of use, and most importantly, the price. In my opinion, the best features StarWind Virtual SAN offers are easy integration with the system installed in the data center. The integration with my existing systems in the data center works well, especially with VMware, as we already have a big cluster in VMware, and the easy integration with that is helpful to solve some problems with the platform. StarWind Virtual SAN has positively impacted my organization by reducing OPEX costs. My OPEX costs have gone down as we reutilize some old servers, and this reduces the CAPEX of hardware in the data center.

Pros

"The onboarding and integrated monitoring tools are pretty good."

"Pure Storage FlashBlade's scalability is one of the most valuable features, and importantly, it always works, allowing for seamless upgrades."

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

"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."

"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."

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

"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."

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."

More Pure Storage FlashBlade pros

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

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

"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."

"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 provides transparency, because of its advanced copy features."

"One of the main features of Spectrum Virtualize is it virtualizes the servers from the storage. We have a very large infrastructure. A major advantage is when you get the aged storage arrays and you have to replace all of those."

"IBM offers excellent customer service."

More IBM Spectrum Virtualize pros

"StarWind is very easy to use, even if you have had no experience using a SAN before."

"StarWind vSAN has allowed us to leverage our server infrastructure more completely without the need to add more hardware."

"StarWind Virtual SAN is a highly flexible solution, as it can be deployed on physical servers or on top of virtual machines running on hypervisors such as VMware vSphere and Microsoft Hyper-V."

"The installation of StarWind Virtual SAN was pretty easy, and the configuration was done in no time."

"Active-active work mode leads to true redundancy of storage and allows us to distribute the load between multiple nodes."

"The fact that I can now count on a true failover solution is what is most appealing."

"StarWind Virtual SAN is a very easy-to-use solution that can be quickly and easily deployed and configured without intimate and specific knowledge in the virtualization sphere."

"StarWind saved us about 80% of our storage costs over our old solution."

More StarWind Virtual SAN pros

Cons

"Its configuration should be easier."

"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."

"I would like to see the licensing fees improved as well as the price per terabytes."

"I would like to see better integration."

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

"I would also like to see better support for CIFS workloads."

"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."

"The documentational aspect of FlashBlade needs improvement."

More Pure Storage FlashBlade cons

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

"I already discussed possible improvements with some of the guys from Hearnsley. One of our frustrations is when you go to expand volumes in a global mirror environment, you have to stop everything in order to expand. So that's one of the things."

"Level 1 technical support needs improvement."

"The Storwize port is not so stable."

"Anything which improves performance and the ability of our systems would be a nice."

"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."

"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."

"t is limited in terms of a single system to eight nodes or four, what they call IO groups."

More IBM Spectrum Virtualize cons

"I would like additional documentation regarding possible networking configurations with 10GbE switching."

"The StarWind Management Console is available only for Microsoft Windows/Windows Server, and should also be available for Linux and macOS, as it would reduce implementation costs."

"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."

"To enable the proactive support capability that is part of our support agreement, I would ask that the terms and conditions be revised and made acceptable to corporate security."

"If it's possible to make a driver/solution that does not make use of the iSCSI targets of Windows, that would be great. I don't know if that's possible, however, it could make the configuration a little easier."

"If there was one thing we could request, it would be the ability to shrink volumes. For example, we want to be able to decrease in the size of the volume."

"It should reclaim white spaces after big files are deleted."

"Besides not being able to use any filesystem, I do not have any additional cons."

Pricing and Cost Advice

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

"We used a reseller for the purchase."

"Licensing fees are paid yearly."

"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 customers have seen a reduction in TCO."

"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."

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

"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

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

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

"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."

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

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

"We would like the CPU cycle to save more on the licensing costs for us."

"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."

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

More IBM Spectrum Virtualize pricing and cost advice

"The scalability limitation for us is its licensing. At some point in the fairly near future, we will probably have to upgrade our license so we can store eight terabytes instead of four. We are currently at four terabytes, but we're starting to knock on the door of that capacity."

"The Price/Performance ratio for this solution is outstanding!"

"Cost is affordable and licensing is smooth."

"The StarWind VSAN business model is very cost-effective."

"The cost takes into account the number of nodes, so the size of the storage is not important."

"StarWind is best price/performance for SMB."

"Licensing is based on nodes rather than TBs, which means that the users are free to increase storage capacity without putting thought into licensing."

"Their pricing seems pretty good, and their licensing structure is pretty straightforward."
