Solutions Architect at Recovery Point Systems

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.

Built-in compression enhances data management efficiency

I have noticed that the technical support for software issues, such as with Spectrum Protect, needs improvement. The case logging process is efficient, but resolving software problems takes too much time. This delay can hinder customers and strain vendor relationships. For hardware issues, IBM handles them efficiently, but software-related support requires enhancement. Overall improvement in support for software cases is necessary.

Gives us a lot of advantages when we need to expand resources

Stability can be improved. Adding all these new features is nice, but we are now at the level where most of the features you need in production are there. The stability is not from a day-to-day operations perspective, but more from a supportability perspective, because currently some of the support scenarios require you to completely evacuate hosts or the complete cluster. That sometimes can be a stretch. This would clearly be an improvement if the support teams were given additional tools to make that easier. Upgradability could be a bit easier sometimes. We are now where vSAN can be updated without ESXi, but there is still enough dependency. So that would be good if that actually would be uncoupled even more. Dashboards are there, and we use vROps as well. So, we have all the beauty of capacity planning and everything over there. That's not really something where we need a lot of other things.

Quotes from Members

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

Pros

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

"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."

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

"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

"The solution provides many controllers."

"The initial setup is pretty easy and simple."

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

More Pure Storage FlashBlade pros

"We are happy with the support that IBM provides us."

"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."

"We acquire companies (and things), so we end up with odd hardware. We bring it behind the SVC and it allows us to migrate stuff off of it seamlessly. SVC can also cover up a host of defects of the underlying storage."

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

"It lowers cost. It does so by getting more efficient use out of the technology behind it."

"Although the GUI from the XIV was used (in my view), IBM has polished and refined the GUI providing a pleasant and easy to navigate GUI experience."

"The ability to have a feature-rich software set which extends the capabilities of the back-end storage arrays."

"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."

More IBM Spectrum Virtualize pros

"vSAN can help customers save on storage system costs, and also save on the human cost."

"VMware vSAN is easy to configure, with basic functionality and the customer can maintain the solution."

"It is easy to find information out there, not only from searching the web, but even the times I have engaged VMware support."

"The flexibility is most valuable. Being able to manage things quickly if something goes wrong is also valuable. Very recently, we had one node that went down due to a power problem, but there was really no major impact on the systems running on top of it."

"It easily integrates with all types of storage."

"The most valuable thing about vSAN is that all of its features have been working well for us for the past two years. We haven't had an issue with them."

"I like that we could choose whatever hardware we wanted, rather than having to use one particular vendor."

"vSAN that has been most effective in streamlining storage operations. For data recovery alerts, it uses tools like snapshots and vMotion."

More VMware vSAN pros

Cons

"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."

"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."

"There could be improvements in public cloud integration."

"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."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

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

"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."

More Pure Storage FlashBlade cons

"The disk reliability is not that good."

"Level 1 technical support needs improvement."

"Adding features for data deduplication is one area of 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."

"In general, the migration is complicated. Though, it is case-by-case."

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

"The training program could be improved."

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

More IBM Spectrum Virtualize cons

"vSAN does not have online dedup. When opening the inline dedupe, the performance will be lower than off inline."

"If we have some complicated issues, you have to use the command lines interface. Not everything is possible to be fixed in the GUI. This is a drawback, that some things have to be fixed via command-line interface and should be able to be done in the GUI."

"The UI could certainly be better. The inside into what's actually going on with vSAN would be nice to know."

"Pricing is something of a concern."

"The server files are larger than before."

"Perhaps they could provide encryption without having to use an encryption manager."

"I would like to see the availability of more template based VMware systems. Combined with the ability to check and measure multiple and converging data segments. Another issue I've seen is that the tool seems to be slow when first starting up."

"Hackers are able to manage to leak information or data from the product using some corrupt files, making it an area of major concern where improvements are required."

More VMware vSAN cons

Pricing and Cost Advice

"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."

"I feel that the price could always be lowered."

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

"The product is very expensive."

"The price is a little high."

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

"We used a reseller for the purchase."

More Pure Storage FlashBlade pricing and cost advice

"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."

"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."

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

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

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

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

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

More IBM Spectrum Virtualize pricing and cost advice

"Basically, vSAN is a license in addition to that of the classic VMware Vsphere, which is also mandatory."

"The price of the solution package depends on the nodes and other factors. The cost some of our customers paid was $500,000. The licensing cost for the components is very good."

"For a classical node plus storage solution, the price is higher."

"The price is expensive."

"I would like to see this technology be made available to smaller businesses, who might benefit from high availability but struggle with the entry fee."

"With the new pricing model, it's expensive for the customer."

"The product's price is not high. The tool is available at a normal price."

"Every product is licensed with full support for a certain number of years. The licensing could be cheaper."
