Disk tiers are comprised of aggregating 1 or more Disk Groups of similar physical disks. The MSA 2040 supports 3
distinct tiers:
1. A Performance tier with SSDs
2. A Standard SAS tier with Enterprise SAS HDDs
3. An Archive tier utilizing Midline SAS HDDs.
Prior to GL200 firmware the MSA 2040 operated through manual Tiering, LUN-level tiers are manually created and
managed by using dedicated vdisks and volumes. LUN level Tiering requires careful planning such that
applications requiring the highest performance be placed on Vdisks utilizing high performance SSD´s. Applications
with lower performance requirements can be placed on Vdisks comprised of Enterprise SAS or midline SAS HDDs.
Beginning with GL200 or newer firmware, the MSA 2040 now supports sub-LUN tiering and automated data
movement between tiers.
The MSA 2040 automated tiering engine moves data between available tiers based on the access characteristics
of that data. Frequently accessed “pages” will migrate to the highest available tier delivering maximum I/O´s to
the application (Performance Tiering). Another feature to the MSA 2040 tiering engine is Archive Tiering where
“cold” or not frequently accessed data can be moved to lower performance tiers. Pages are migrated between
tiers automatically such that I/O’s are optimized in real-time.
The Archive Tiering functionality is provided at no charge on the MSA 2040 platform beginning with GL200 or
newer firmware. The Performance Tiering capability utilizing a fault tolerant SSD Disk Group is a paid feature and
requires the below SKU to enable it. Performance Tiering from SAS MDL (Archive Tier) to Enterprise SAS(Standard
Tier) drives is provided at no charge.

VMware Site Recovery Manager (SRM)
VMware vCenter Site Recovery Manager (SRM) is an extension to VMware vCenter that delivers business-
continuity and disaster-recovery solution that helps you plan, test, and execute the recovery of vCenter virtual
machines. SRM can discover and manage replicated datastores, and automate migration of inventory from one
vCenter to another. Site Recovery Manager integrates with the underlying replication product through a Storage
Replication Adapter (SRA). The SRM is available only for linear storage.
HP MSA 2040 Site Recovery Adapter (SRA)
The MSA 2040 SRA, a free-to-use plugin, is the program that integrates the VMware vCenter SRM with HP MSA
2040 arrays. It enables full-featured use of the VMware SRM. It is a host-software component installed on a
Microsoft Windows Server that enables disaster recovery management (DRM) software on the host to
communicate and control certain aspects of the replication feature in storage systems connected to the server. It
allows the VMware SRM software to automatically coordinate virtual machine failover and failback between a
protected data center and a disaster recovery site by employing a disaster recovery solution called Remote Snap.
A perfect combination of the Remote Snap replication and VMware SRM provides an unfailing automated solution
