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.

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.

Quotes from Members

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

Pros

"There are many benefits to this solution. Storage virtualization and the ability to migrate massive amounts of data to other systems without impacting your client are the most valuable. It is non-disruptive for my users. We migrated 350 terabytes of data in one night to a new machine without a small system going down and a single user complaining about the performance. You have to fine-tune a lot of storage machines constantly for performance and for making sure that they are optimal, but IBM Spectrum Virtualize does this by itself. It does the adjustment on its own, and it does it right. That's what makes it different. I had a huge VSP from Hitachi, which is also a type of virtualization-based engine but with a decent size. It was a continuous performance-tuning exercise. I never had that issue with IBM Spectrum Virtualize."
"We can failover easily, because a lot of our data is replicated from family to the second replication."
"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."
"It lowers cost. It does so by getting more efficient use out of the technology behind it."
"IBM provides exceptional technical support, which I rate as the best along with Cisco."
"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's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."
"The scalability is very good. It can handle anywhere from very small to large enterprise class."
"I would rate Pure Storage FlashBlade a ten out of ten."
"Among its most appealing features are its ease of handling and minimal maintenance requirements."
"The initial setup is pretty easy and simple."
"We can capacity plan at a greater level than we used to."
"It performs well and it is also very fast."
"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 feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."
"The onboarding and integrated monitoring tools are pretty good."
 

Cons

"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."
"The training program could be improved."
"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."
"Anything which improves performance and the ability of our systems would be a nice."
"Adding features for data deduplication is one area of improvement."
"The Storwize port is not so stable."
"The integration would be an option that we would like, but I understand that's not how it's going to be implemented."
"Level 1 technical support needs improvement."
"The documentational aspect of FlashBlade needs improvement."
"Its configuration should be easier."
"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."
"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."
"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"They need better integration with public clouds along with a better hybrid solution."
"The feature that we're waiting on is better integration with the cell services."
"I want efficiency. FlashBlade doesn't have efficiency now."
 

Pricing and Cost Advice

"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."
"I think it is a good value for the price."
"We would like the CPU cycle to save more on the licensing costs for us."
"Do a proof of concept, if you are not comfortable jumping in, but do it."
"This solution came as an additional cost for the TSM package we chose."
"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."
"The entry point of pricing for this product is the most amazing price ever in the industry."
"The pricing for FlashBlade is between cheap and moderate."
"I feel that the price could always be lowered."
"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."
"The product is very expensive."
"We used a reseller for the purchase."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
