New Infrastructure on IBM SONAS 1.4.1

IBM Scale Out NAS (SONAS) 1.4.1 introduces a new storage infrastructure based on the IBM DCS3700 storage controller and expansion units.

SONAS Storage Controller 2
(IBM Machine type model 2851-DR2)
This storage controller is a 4Ux60 disk drive storage controller with redundant RAID controllers, redundant power supplies and cooling modules, and HDD slots for sixty 3.5-inch or 2.5-inch HDDs or SSDs.

Two types of RAID controllers are available:

Base RAID controller
Performance Module controllers (feature #3100)

With the base RAID controllers, two cache memory sizes are available (4GB and 8GB per storage controller). With the Performance Module Controllers, three cache memory sizes are available (12GB, 24GB, and 48GB per storage controller).

SONAS Expansion Unit 2
(IBM Machine type model 2851-DE2)
This expansion unit is a 4Ux60 disk drive expansion unit with redundant environmental services modules (EMSs), redundant power supplies and cooling modules, and HDD slots for sixty 3.5-inch or 2.5-inch HDDs or SSDs.

This storage controller and expansion unit are able to be ordered with a SONAS system and configured as a SONAS gateway attached storage system. The EMS upgrade process will support additional storage controller and expansion units, and they will be configured at the customer location as SONAS gateway attached storage.

SONAS 1.4.1 supports Active Cloud Engine (ACE) WAN caching between a SONAS system and one or more Storwize V7000 unified systems. GUI enhancements have been made for configuring ACE WAN caching relationships.
