Support for SSD Storage

The SPARC Enterprise T5440 server can now use 32GB SATA SSD for internal
storage. The SSDs are hot-pluggable and can be used in place of or in combination
with 2.5-inch SAS hard drives. The current 2.5-inch drive tray is fully compatible
with these SSD units.
Note – You can install a maximum of 3 SSDs in the T5440 server. When using the
external storage unit for the system disk, up to 4 SSDs can be installed.
For instructions on installation and removal of SSDs, see the "Hot-Plugging a Hard
Drive" described in the SPARC Enterprise T5440 Server Service Manual. The
procedures apply to both the disk-based hard drives and SSDs.

Using a SSD as a Boot Device

You cannot use a SSD as a boot device.

About the Cache Setting of SSDs

The SSDs have a setting of internal cache enabled in the initial status. When used in
the cache enabled condition, data may be lost at the time of power failure.
You can disable the internal cache by using a sub command cache of format -e
command after booting the Solaris. This setting is not saved when you reboot the
Solaris.
To ensure data integrity, it is recommended to use an uninterruptible power supply.
