Store Hits

Reports

The Performance - Data Store Hits report summarizes how many times the HP EFS WAN Accelerator data-store disk and memory have seen a data segment. A hit is a data segment that has been seen before by the data store in the HP EFS WAN Accelerator. If a hit has occurred, the HP EFS WAN Accelerator sends the reference to the data segment rather than the actual data over the WAN.

The Performance - Data Store Hits report contains the following table of statistics that summarize data store activity.

Field	Description
Total Hits over Last Week	Specifies the total number of hits against the data store. A hit
	is a data segment that has been seen before by the data store
	in the HP EFS WAN Accelerator. If a hit has occurred, the
	HP EFS WAN Accelerator sends the reference to the data
	rather than the actual data over the WAN.
Misses	Specifies the number of misses that occurred. A miss is an
	unmatched data segment—the data store has not seen the
	data segment before and must send all the data across the
	WAN. The data is Lempel-Ziv (LZ) compressed if LZ
	compression is enabled. For detailed information about
	setting optimization policies, see “Setting In-Path Rules” on
	page 25.
