Turbocharge your applications without compromise - using HP 3PAR StoreServ 7450 Paul Haverfield Principal technologist HP Storage APJ region June 25 th 2014 @paulhavs
No Compromises http://www.techopsguys.com/2014/06/09/3par-june-2014-the-7450-afa-keeps-getting-better/ At the end of the day the 3PAR flash story has evolved into one of no compromises. You get the low cost flash, you get the inline hardware accelerated deduplication, you get the high performance with multitenancy and low latency, you get all of that and you re not compromising on any other tier 1 capabilities (too many to go into here, you can see past posts for more info). You re getting a proven architecture that has matured over the past decade, a common operating system, the only storage platform that leverages custom ASICs to give uncompromising performance even with the bells & whistles turned on.

Summary of HP 3PAR Thin Technologies 3PAR Thin Technology relies on a Fast Lookup Table: 3-level implementation akin to Virtual Memory lookup tables. Designed for fast, scalable pointer lookups, powered with Express Indexing technology. Deduped and Zero pages references are stored in these lookup tables Thin Technologies uses a reservationless, dedicate-on-write approach that draws and configures capacity in fine-grained increments from a single free space reservoir without pre-dedication of any kind. In contrast to competitive thin provisioning implementations, 3PAR Thin Technologies can be used with high performance I/O workloads. HP 3PAR Thin Technologies are completely automated.
