ZIL SSD Upgrade

The ZIL SSD upgrade adds two 200GB SSDs to the VSM 6 storage pool. These SSDs are dedicated to the ZFS intent log (ZIL) to improve synchronous write performance by speeding up specific synchronizing events. This upgrade is only available for VSM 6 configurations with four or more disk shelves installed.

The ZIL performance upgrade for VSM 6 systems with 4TB disks is for VSM 6 units with approximate production dates of December 2013 to present. The Oracle service person can confirm the VSM 6 configuration.

The ZIL performance upgrade for VSM 6 with 3TB disks is for VSM 6 units with approximate production dates of November 2012 through November 2013. The Oracle service person can confirm the VSM 6 configuration.

This upgrade is recommended for certain VSM 6 configurations with Host workloads involving small (1MB to 2MB) VTVs and a high number of simultaneous VTV mount operations. For these workloads, adding SSDs to the VSM 6 storage pool significantly improves performance.
