D4T79A is the HPE MSA 2040 Performance Auto Tiering license. An SSD Performance Tier that handles both reads and writes cannot be created on an MSA 2040 virtual storage pool without it. The license is not needed on linear storage configurations that do not use Virtual Storage disk groups and pools.
The MSA 2040 works with three tiers: a Performance tier of SSDs, a Standard tier of Enterprise SAS drives and an Archive tier of midline SAS drives. Automated sub-LUN tiering and movement of data between tiers begin with GL200 firmware. Moving data from the Archive tier to the Standard tier needs no license.
Four MSA ES flash bundles each include one D4T79A together with four MSA SSDs: P9H23SB (800GB, SAS dual controller SFF), P9H24SB (400GB, SAN dual controller SFF), P9H25SB (800GB, SAN dual controller SFF) and P9H26SB (400GB, SAS dual controller SFF). The MSA Data Services Suite, Q0H99A MSA Data Services Suite, also includes a Performance Tiering license. The alternate number for this license is D4T79AE. More arrays and options are in HPE storage systems.
