Overview tab

The Overview tab summarizes key information gathered from all ioMemory storage devices, including IOPS, Reserve Space, and Temperature.

Current alerts appear on this tab.

Operations

Shows a historical trend of IOPS for all devices being managed by the HP IO Accelerator Management Tool.

Reserve Space

Reserve Space (as shown on the Overview tab) displays helpful information regarding the health of the device being monitored as determined by the percentage of reserve space available. The reserve space decreases as NAND blocks are retired, with write operations tending to wear out blocks faster than reads do.

An early warning message is sent by the driver when the amount of reserve is close to reaching the 10% available threshold. If the reserve space decreases to 0% of its original size, the device enters write-reduced mode (degraded) in order to prolong the lifespan of the device. Sometime after the reserve space is depleted, the device enters read-only mode and no further writes to the device can be done. If crossed, these thresholds and their accompanying messages should provide ample time for you to back up and migrate data on the device.
