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

Pros
We are a 100% satisfied with the stability of the solution.Stability-wise, this solution is fine.The feature I find most valuable, is the deduplication, because the nature of the data that we are using in our current environment, has a lot of replicated data.The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate.The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration.The FS900 uses custom built flash modules offering with better latency, and is also denser packed then most modular all-flash arrays using commodity SSDs.An easy interface to set up, good build quality, and easily accessible parts for hot swapping combined with sub 500 us latency under heavy load.The initial customer technical support was efficient and effective.

This product is perfect for small, and mid-range customers who need to pay less, but still, get enterprise-level capabilities.This solution makes it easy to manage storage, provision new workloads, and scale-up.The All-Flash models are pretty fast for the vast majority of our remote workloads.We use replication for disaster recovery (DR), making our DR process much easier.It has reduced complexity.We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint.It has good performance.We can get almost real-time response times.

We prefer the SR650 server system. This version fits our customers' needs best. That's the latest update that we can try to give them.The FlexClone feature is the solution's most valuable aspect.

Cons
I think the only thing the developers can look at, is that it is limited to 25 gigabytes currently. In the next release they might want to increase that.This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method.I would like to see an improvement in the handling of large amounts of rights.The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general.The solution is not able to replicate data in one-to-many scenario.When we performed some HW fault tests under heavy load, we found that some of the parts (fan units and PSUs) should only be removed from the airflow for a short time (less than a minute) when replacing.Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR.

This product needs to have better integration with enterprise backup solutions and archiving devices.This solution would be improved with the addition of flexible raid volumes.We would like to see the concept of Storage Groups brought back to this product line.I haven't seen the roadmap for this solution.It is missing some features, like deduplication.Because we can do synchronous replication between the two sites, this made the setup challenging for this piece. They did not know how to set this up initially. We ended up having to do bidirectional synchronous replication.I would like them to continue to build on the solution and expand on the functionality, like replication.We'd like to see a cheaper version of an all-flash array in that footprint.

Technical support could be improved for this solution.The solution needs a simpler licensing theme around the DM series. The problem is if you only need one of the features, you still have to buy the whole thing. The licensing needs to be more granular or flexible so you have the option to only license FlexCone or Inline Compression features.

Pricing and Cost Advice
For a yearly license, it is about $100,000. There are no additional costs. The entire system is included.

Our CAPEX was close to $42,000 and operating costs are below $1000.Our costs are roughly $200,000 a year.The solution is extremely functional for the price that we pay for it. It is worth the investment.We purchased a five-year warranty.Compression is making a difference towards the amount of hardware that we need to purchase.The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes.It scales, but then you have to buy additional stuff.With the large Unity that we bought, it has saved us about one and a half rack space. That's our return on investment on our flash array. We also need less Fibre Channel connectivity.

We can try to make a good offer for our customers, but in Turkey the difference between the dollar and Turkish lira is very high. Pricing is the hardest part of my job, because the price is very high for our customers. We try hard to make the price low for our customers.
