Capacity Summary - HP ProLiant DL980 G7 Technical White Paper

Technical white paper | HP ProLiant DL980 G7 and P2000 G3 MSA Storage

Capacity summary

Several data capacities are cited in this document, including Maximum Data Capacity, and Fast Track Rated Database
Capacity. The following summarizes these values:
Maximum Data Capacity: This is raw data space minus the required minimum space for TempDB database files, multiplied
by the Fast Track compression factor (3.5). This capacity does not take into account primary staging space, or disk
headroom.
Fast Track Rated Database Capacity: This is the optimal, Fast Track certified data capacity of the configuration. Maximum
rated performance of the system is valid when Fast Track data does not exceed this capacity.
Table 4 summarizes the configuration specifics and capabilities of the fibre channel version of the P2000, the P2000 G3
MSA FC dual controller SFF array system.
