VMworld 2014 at Moscone Center in San Francisco, August 24 to 28, has many new products and capabilities to help our customers achieve greater efficiency and availability with infrastructure virtualization. Some solutions that HDS will highlight in our booth include the following:
The global active device (GAD) feature that we announced with our VSP G1000 storage array on April 23 of this year has been released for General Availability after extensive testing of its use for both block and file storage by several key customer accounts.
Continuing from my last blog where I shared my views on the passing fad of stand alone storage solutions, like all-flash-arrays and file sync and share solutions that are not integrated with enterprise systems, I see tremendous adoption for new storage technologies like Virtual Volume (aka VVol). VVol, from VMware, which enables the integration of [...]
“A logical partition, commonly called an LPAR, is a subset of computer’s hardware resources, virtualized as a separate computer. In effect, a physical machine can be partitioned into multiple logical partitions, each hosting a separate operating system.” from Wikipedia
In my blog post that supported the announcement of the VSP G1000 with SVOS, Storage Virtualization Operating System, I described VSP G1000 as a unified storage platform that can provide approximately 4 million random reads for 8KB blocks or more than 1.2 million NFS operations for file.
As servers increase their number of cores and memory performance, VMware is able to scale up additional virtual machines and drive more applications almost indefinitely. Unfortunately, each virtual machine adds additional random I/O workload, and the storage systems become a bottleneck. While VMware has tools like vMotion and Storage vMotion to rebalance the workload and [...]
Hitachi Data Systems announced a new global active device capability within the new Storage Virtualization Operating System (SVOS) and the new Virtual Storage Platform G1000 (VSP G1000) storage system. This enables a virtual device to span two VSP G1000 storage systems that are separated by up to 100 KM apart for load balancing and active/active [...]
Storage security is getting more attention as I outlined in my top 10 trends post in December. In that post I talked about the availability of data encryption in the backend directors of Hitachi storage systems, VSP, HUS VM and HUS 150 with local or external key management. This encryption was designed into our storage [...]
Many data centers purchase storage infrastructure on a 3 to 5 year depreciation cycle. The problem with buying storage this way is that you have to buy more than you need for the first few years. These data centers have to over provision their storage requirements with capacity that is declining in price by about [...]
Laura DuBois of IDC has been calling attention to the explosion of data copies problem since 2012 and I have blogged about this several times, including my top ten trends for 2013 and 2014. Her latest report on January 31 of this year reconfirms that 65% of external storage systems capacity is used to store [...]
