As I have stated in my previous posts on data center transformation, virtualization plays an important role in creating a dynamic pool of server and storage resources and masking the physical infrastructure from the application, so that the provisioning, movement, and refresh of the infrastructure can be done without disruption to the business. While [...]
After my last post on Data Center Transformation Part 4: Dynamic Provisioning, where I talked about the benefits of Hitachi Dynamic Provisioning, Lucas Mearian from Computerworld wrote an article “A waste of Space: Bulk of drive capacity still underutilized – Most companies can reclaim as much as 60% of their storage Capacity with Monitoring and [...]
A while back we did a storage assessment for a non HDS customer and showed him that his storage utilization was actually around 30% which is typical in most accounts. While that was not surprising to the operations people this was a surprise to the financial people who could not understand why 70% of their [...]
I recently spoke to two storage analysts about the effect of server virtualization on storage resources. Both agreed that the effect of virtual machines will be to increase the I/O workload coming from the VM hardware platform by the number of VMs that are virtualized and that the resulting I/O would be very random.
All thin provisioning implementations have overhead associated with tagging and mapping the chunks or pages that are used to provision a virtual volume. Some also have additional overhead to handle the RAID protection that supports these pages or chunks. In this post I will explain what Hitachi does to address these overheads.
This year I have been seeing more and more of our USP V customers turning on their Hitachi Dynamic Provisioning license and enjoying the benefits of thin provisioning. One web B2B was able to half their existing storage down to 4 frames while increasing their usable TB from 133 to 236 TB. While the amount [...]

This morning Hitachi Data Systems announced some new enhancements to the AMS 2000 modular storage platform. These new enhancements include Dynamic Provisioning, Dense Expansion Trays, AMS 2500DC for NEBS compliance, 8Gbs FC storage ports, and security enhancements. Since we began shipping the AMS 2000 platform in October of [...]
USP V users are finding it easy to free up 30% to 40 % of existing storage capacity with Hitachi Dynamic Provisioning. The best part is that they can convert their current “fat”, over allocated, volumes to thin provisioned volumes with, no down time to do migration, no rezoning of the SAN, and little or no [...]
