High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

High availability and user-friendliness enhance infrastructure health and redundancy

I would rate technical support from DataCore SANsymphony a 10. Each time I contact the technical support, it's when I don't have a choice because it's very difficult for me on site, and each time, I have good people online who are able to help me solve the problem. Usually, the problems are not very technically difficult, but sometimes they are, and the support team is still there to help us resolve them. The majority of the problems are linked to licensing, so when the license has expired or the number is not correct, they are proactive and change things live, which is very good.

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

"The initial setup is pretty quick."

"The most valuable feature of this solution is performance."

"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

"It is very easy to use, and it is very fast."

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

"The most valuable feature is Safe Mode."

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

More Pure Storage FlashBlade pros

"It is a well-proven, automated management tool in all dynamic provisioning, auto-tiering, great performance, parallel I/O, cache speed mechanism, etc."

"The dashboard is very intuitive, and there are a lot of counters to diagnose what happens during a short period (like when a backup is in progress)."

"It's a software storage solution that can scale as we like. There is also has a parallel feature that enhances the performance of the storage solution. We can separate storage and computing, and we can scale these two parts of the platform to meet business needs efficiently."

"The most valuable feature for us is that we can adjust the size of the storage very easily, without stopping production."

"This flexibility and scalability have helped our organization in practice because it is important for us as it decouples the storage management software from the physical hardware, creating a software layer of intelligence."

"Our system is designed to be scalable and flexible, so it can grow and adapt to meet the changing needs of our clients."

"I am very happy with this product's ability to adapt, increase, and modify existing infrastructures."

"The most valuable feature of DataCore SANsymphony SDS is its high availability. This solution also exhibits good performance and has high stability."

More DataCore SANsymphony pros

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

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

"It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."

"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."

"The most valuable features are the simplicity of use, the flexibility, and the options included. I mean, it's just a big time saver."

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

More IBM Spectrum Virtualize pros

Cons

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

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

"I would like to see more monitoring capability included in the next release of this solution."

"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."

"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."

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

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

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

More Pure Storage FlashBlade cons

"There is room for improvement in the graphical interface."

"It would be ideal if they were providing archive licensing with the ability to create a second pool on existing storage nodes."

"I found it a little unnecessary to have to rename the configurations within the graphics console in order to have unique names."

"The graphical interface is not always very stable."

"My experience with pricing, setup cost, and licensing is that in many cases it is expensive, but we can find a solution every time to have a discount for selling it."

"The solution could be better packaged and marketed."

"If it could integrate to a cloud gateway, then we could carry it directly to storage, instead of having middleware in between the storage and the cloud."

"NVMeoF should be implemented. This protocol will play a major role in storage infrastructure in the future."

More DataCore SANsymphony cons

"The training program could be improved."

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

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

"The disk reliability is not that good."

"For improvement considerations, I would probably say multiple sites."

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

"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."

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

More IBM Spectrum Virtualize cons

Pricing and Cost Advice

"The price of this solution could be made more affordable."

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

"Our licensing is renewed annually."

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

"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."

"The price could be cheaper."

"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."

More Pure Storage FlashBlade pricing and cost advice

"The solution is cost effective."

"The pricing and licensing are better with DataCore."

"DataCore SANsymphony's pricing is very high and should be much cheaper."

"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."

"Pricing has improved but it is still expensive."

"It is relatively expensive, and the additional costs for hardware and storage can make it a significant investment for customers."

"This product has a good ratio between quality and price. In many cases, it's less expensive to work with DataCore than other storage systems."

"The cost is at the same level as other storage solutions and it is easy to understand the licensing."

More DataCore SANsymphony pricing and cost advice

"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."

"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."

"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."

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

"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."

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