I have been in this business for more than 20 years. Before Hitachi, I worked with storage solutions by various brands, including NetApp, EMC, and IBM. The competing solutions are also good, but they may not be suitable for all use cases. 

We are also partners with Dell EMC and NetApp, but since forming a partnership with Hitachi, we predominantly recommend their products to our customers. We still have a small number of customers using NetApp as well, but it's relatively low. We primarily work with Hitachi because of their reliability and sturdiness.

I have used Dell and VMware.

One key feature is storage utilization. Hitachi VSP can utilize storage from any vendor, unlike Dell or HPE.

For example, if I have old Dell storage that needs migration,  Hitachi can virtualize it seamlessly. Other vendors might require third-party tools for such migrations.

We had a Hitachi solution as well, before this one. When doing our assessment of the solution, we had a dedicated Hitachi partner who helped us to check into the IOPS and latency.

I worked on different solutions but not with the customers I deal with currently. I have worked with different companies, older versions, and models of Hitachi Virtual Storage Platform and other storage tools. Everything depends upon the customers' needs.

We have used NetApp, HyperFlex, and vSAN—a lot of solutions. We switched because our main infrastructure is Hitachi and we wanted to keep it all with one vendor.

We had another Hitachi system. I don't remember the model, but it was hybrid storage.

We have experience and history with several Dell EMC products including the BNX line, BMX,  and PowerMax. However, we are moving away from this to the HP all-flash solution.

The only reason we changed from the Hitachi Platform G is that it was getting long in the tooth, and we wanted to get into the flash environment. 

We have an older version of Hitachi, which is also a virtual storage platform but not the G Series. Also EMC VMAX 

Over the past seven years, we used three different versions. We started with the VSP, then upgraded to the G1000, and then the G1500 was the most recent one.

We used the Dell EMC DMX series, as well. All the software products that we had, we were comfortable with when we were on the EMC DMX series. So, after switches, it was all the same kind of software and functionality that we were used to. It wasn't really over and above what we had with EMC at the time, but rather just more of the same.

The reason we switched is that after putting out an RFP, we evaluated options based on the technology and pricing. Hitachi was the winner.

I have experience with several enterprise storage solutions.

We worked with HP products before switching to Hitachi. The Hitachi product had everything we needed for our customer demands and we think it is a better solution.

We have used Hitachi high-end storage products for many of the past fifteen years as the primary storage resource for our enterprise clients. About ten years ago, we were struggling with Hitachi's local sales force not being proactive/value-added enough, so we made the decision to introduce another storage vendor (NetApp) into our infrastructure. The two vendors continue to coexist and compete today in a positive way.  

The previous solution was a sync-based solution storage system. It wasn't active/active and before that, we used EMC VPLEX in another environment. We tested the active/active feature benefits. 

One of the main demands for this particular solution was to be active/active. At that time, the only vendors that offered an active/active machine were EMC and Hitachi.

The previous solution was Hitachi but it had spinning disks. We went to all Flash for the performance.

We have used BMC and Hewlett-Packard before.

Based on customers need solutions should be designed. In my experience switching from previous brands to HDS VSP has led to reaching 40% better TCO and 99.9999 availability.

It depends on the circumstances. We choose different storage products based on the business needs and in my opinion, there is no solution that can meet all customer needs.

We use low-cost SAN storage for some needs, such as Archie Data, and in some other cases, like the core business software, high availability levels are very important so higher-level SAN storage is used.

Previously we used IBM systems. We switched to Hitachi about 20 years ago.

Prior to this, we were using the IBM V3700 series, and we upgraded from that to the Hitachi.
