Hitachi Data Systems’ (HDS) AMS 2000 series got a touching up today with the announcement of some incremental updates to the midrange disk array.
HDS is making two updates available now – a new High-Density Storage Expansion tray and a NEBS-certified DC power option for the 2500 model.
The High-Density Storage Expansion Tray holds up to 48 one-terabyte SATA disk drives in 4U; existing AMS trays hold 15 SAS or SATA drives in 3U. The maximum number of drives supported in the 2500 (480) hasn’t changed, but the maximum configuration now takes up one less rack than with the 15-drive trays. Good news for users focusing on storage and energy efficiency. A fully loaded high-density tray is listed at $83,260.
The AMS 2000 series has had the option of running on battery power (DC) since the arrays were first announced last fall, but the new 2500DC model has been certified as compliant with the Network Equipment Building System (NEBS) standard for use in telecom and other “lights out” environments.
According to HDS senior product marketing manager Mark Adams, there’s little technical difference between the certified and non-certified versions, but the certified version “has been proven operational through intense earthquake activity” and certified by an independent lab. Another difference between the NEBS-certified and non-NEBS certified models is the price: the compliant list price is $102,870, while the non-compliant list price is $92,500.
Later this year, HDS will make 8 Gbps Fibre Channel host ports available for the AMS 2300 and AMS 2500 models (internal disks will remain SAS or SATA). Security features to become available in the second half of 2009 include support for external authentication, meaning the AMS array and authenticating server don’t have to reside on the same network. Finally, as announced last week, HDS is extending its Dynamic Provisioning (HDP) software to run on the AMS in addition to the high-end USP-V.
User Matt Stroh, SAP business administrator for Wisconsin-based Industrial Electric Wire and Cable (IEWC), said he’s looking forward to deploying thin provisioning for the AMS 2300 he bought to replace an EMC Clariion CX-300 and HDS AMS 500 at the beginning of the year. “I’d like to get my hands on that as soon as possible,” he said. “We have a lot of file systems just storing SAP and Oracle binaries, and I don’t need much storage for them, but I’ve been giving them a big chunk anyway.”
While dynamic provisioning is going to be available for AMS, the Zero-Page Reclaim feature recently announced for the USP-V version of HDP will not be available for the forseeable future, according to HDS officials, who have not disclosed a technical reason why that’s the case.
