In my experience, I've encountered several limitations, particularly in the operational tasks, when dealing with unified storage. I've faced significant performance issues, especially when extending block capacities. The operational challenges, such as the console getting blocked and preventing any activity, have been a recurring issue.
For instance, extending a replicated volume from one site to another involves breaking the mirror application, adding unnecessary complexities. Unlike other products, like Dell, where extending volumes is straightforward, this process on this platform requires multiple steps, including breaking and reestablishing the application, making it time-consuming and not straightforward.
The Hitachi Virtual Storage Platform faces challenges when it comes to features like deduplication and compression. Enabling these features can lead to processor overload, resulting in performance degradation, especially under high loads.
It faces limitations, particularly during code upgrades. If the CPU utilization exceeds 65 percent, the standard procedures for firmware or code upgrades are restricted.
I have been working with the product for four years.
I rate the product’s stability a five out of ten.
There are no significant challenges in terms of scalability, and it can accommodate larger storage capacities compared to other storage solutions.
The support experience with Hitachi VSP is characterized by a lengthy process for issue resolution. For a simple problem, the support team typically requests logs, which take about 30 minutes to generate. Uploading the logs adds another 30 minutes, and the engineer's review of the logs requires an additional hour. Consequently, the entire process takes two hours, leaving the system in a critical state without a resolution during that time.
I rate the product’s deployment one out of ten. The deployment process lasted for three months.The initial deployment encountered numerous performance issues, leading to instability and frequent disruptions in production. The on-site engineering team was actively engaged for almost three months to address and resolve these challenges.
The integration process of Hitachi VSP into the existing IT infrastructure is not straightforward and is a bit complex.
The initial deployment was initially attempted by a third party, but they were unsuccessful in resolving the issues. Subsequently, Hitachi engineers were directly engaged and worked on-site for nearly three months, facing challenges throughout the process.
The solution is expensive.
I rate the overall product a four out of ten.
