HPE Brings Nimble Skynet to 3PAR Arrays

Who doesn’t like the idea of having six 9’s of uptime for their storage?  Availability is a major consideration for any storage, public or private.  Of course, having great availability isn’t the only measure of storage quality.  We also value performance, low latency and consistency.  But making storage behave in a predictable manner isn’t always… Read more »

Last week Martin and I had a great conversation with Kieran Harty, CTO of Tintri Inc.  Tintri sells a range of storage appliances that deliver VM-focused shared storage.  Rather than talk exclusively about products, we discussed how storage arrays are evolving to meet the needs of private cloud. Requirements The NIST definition of public cloud… Read more »

Flash Tiering – HP 3PAR Adaptive Cache

I recently completed a white paper for HPE on a new feature in the 3PAR StoreServ platform called Adaptive Cache.  In disk-based 3PAR systems, flash SSD devices can be used to augment the DRAM cache.  This acts like a second level of memory tiering by cascading cached pages to flash rather than simply flushing them… Read more »
