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.

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

"We can capacity plan at a greater level than we used to."

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

"The initial setup is pretty easy and simple."

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

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

"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 main feature I have found to be product replication."

More Pure Storage FlashBlade pros

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

"Migration from configurations where servers have storage provisioned from older SAN disk systems to newer storage systems is almost seamless using image mode migration techniques, with only a short outage of the servers."

"The SVC gives excellent performance with tiered storage behind it."

"In my opinion, the quick restore, the low latency, and the ease of use are some of the most valuable features."

"When we add storage behind it, the product is good for the customers because their customers do not notice that anything is happening due to the virtualization."

"Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places."

"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."

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

More IBM Spectrum Virtualize pros

"With StarWind's Proactive monitoring we can go about our day helping our customers and not have to worry about our cluster's health."

"The low cost of this solution has also made a big difference in our budget, which has been very helpful."

"Being able to upgrade machines and software during business operations just by switching nodes has been a huge improvement. We"

"Reliability and overall uptime are key as we're also hosting client environments in addition to our own."

"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."

"Product functionality and performance are wonderful."

"The full suite of redundancy gives a nice sense of security for the whole environment."

"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."

Cons

"It's on the expensive side, as expected for a niche product."

"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."

"It would be nice if you could store file-based in the same box with the same technology."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"They need better integration with public clouds along with a better hybrid solution."

"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."

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

"I have not seen ROI."

More Pure Storage FlashBlade cons

"Level 1 technical support needs improvement."

"There are things that occur when you get to this size and capacity. We're very large, i.e., petabytes. When you get to that sheer volume of the numbers of things, it is too big for people to keep track of."

"I would like to see them provide a unified platform that offers block, file, and object-based protocol access."

"NBME support and support for a higher Fibre Channel lengths could be improved, but those are already on the roadmap."

"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."

"Tighter integration with cloud storage might be useful as a target for a variety of use cases."

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

"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."

More IBM Spectrum Virtualize cons

"Although the setup documentation was very complete and succinct, I found StarWind documentation to be a bit sparse."

"I would request that the terms and conditions be reviewed and made more acceptable to corporate security so that we could finally turn on the proactive support feature, as it is included with our support agreement."

"The only thing I have run into is that I did want to add more hard drives into the host, so that we could look at doing a RAID 10, and the hard drive prices were pretty expensive... that's pretty nit-picky and I don't think it has anything to do with StarWind itself. I think it's more on whomever they work with for their hardware."

"The only issue we have had was the issue of performance, however, that is only due to the fact that we purchased a mix of SSD and regular spindle drives, and restoring databases was slow as it was trying to restore the database using the spindle drives."

"What would have to be done urgently is the adaptation of the hardware to the configuration."

"It would be amazing if there was, perhaps, a more automated process for updating the hosts themselves, although the maintenance mode works well."

"It would be nice if the software told you a new version was available and prompted you to do the upgrade to keep everything up to date."

"The response time is usually several hours after the issue occurred."

Pricing and Cost Advice

"The price is a little high."

"The product is very expensive."

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

"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."

"The pricing for FlashBlade is between cheap and moderate."

"Our licensing is renewed annually."

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

More Pure Storage FlashBlade pricing and cost advice

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

"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."

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

"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."

"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."

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

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

More IBM Spectrum Virtualize pricing and cost advice

"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."

"This was all completed at an affordable price point for an SMB, which was also a key element for an NPO."

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

"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."

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

"It's an all in one package, making it very easy."

"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."

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