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.

Quotes from Members

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

Pros

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

"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 most valuable feature of this solution is performance."

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

"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."

"It uses the same platform for connectivity so integration is seamless."

"It performs well and it is also very fast."

More Pure Storage FlashBlade pros

"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."

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

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

"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."

"IBM offers excellent customer service."

"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."

"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 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."

More IBM Spectrum Virtualize pros

"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."

"The best part of the solution is that you can actually scale up to a large number of operating systems without additional hardware."

"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."

"The most valuable features of the solution are that it is easy to deploy and the support is really good."

"The solution is simple to configure and provides good performance and less footprint."

"This is an easy-to-use product for adding flexibility to your storage solution."

"VMware Software Defined Storage gives higher availability against data corruption."

"The single management panel is the main feature that is wonderful for the customer."

Cons

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

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

"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."

"There could be improvements in public cloud integration."

"I would like to see more VM-Aware features in the next release of this solution."

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

"Pure Storage FlashBlade should improve on more cloud integration."

"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."

More Pure Storage FlashBlade cons

"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."

"The training program could be improved."

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

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

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

"The disk reliability is not that good."

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

"Level 1 technical support needs improvement."

More IBM Spectrum Virtualize cons

"The performance is not as good as some competing products and reporting can be improved."

"VMware Software Defined Storage should include a shared database on a standard version."

"The license model of the product is an area of concern where improvements are required."

"There is room for more integrations and plugins into more storages."

"I'd like to see improved hardware compatibility"

"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."

"It doesn't have the ability to be deployed on any kind of hardware and network connectors."

"Simplifying the licensing model and making it cheaper would improve the solution."

Pricing and Cost Advice

"Licensing fees are paid yearly."

"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."

"Our licensing is renewed annually."

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

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

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

"I rate the tool's pricing a seven to eight out of ten."

"The price could be cheaper."

More Pure Storage FlashBlade pricing and cost advice

"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."

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

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

"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."

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

"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."

"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

"A single socket costs you around US $6,000 for three years. At a minimum, you have a three load cluster for a medium or enterprise-scale company. It can get quite expensive because you're likely to need four to six sockets on the other side. It comes to around $30,000."

"VMware Software Defined Storage is a slightly expensive solution."

"The solution is very expensive."

"I believe there is a yearly licensing fee of around $2000 - $5000. I don't think there are additional costs above that but it depends on the type of infrastructure you're booting."

"The product is quite expensive and is among the most expensive for this type of solution."
