SunFire X4500 SATA driver Hi, I am Lida Horn, a Solaris engineer who has
been working on new driver technology for Solaris 11
(aka Nevada, aka OpenSolaris) and Solaris 10 Updates 2 & 3.
This is a new driver for Marvell SATA controllers.
The marvell88sx driver takes advantage of the SATA features and performance
including hot plugging and 3.0Gb/sec transfer speeds.
This driver utilizes the new SATA framework which does
SCSI to ATA translation. This allows virtually all of
the functionality of the sd (SCSI Disk) driver to be
utilized. Further, SMART capability is built in for
additional reliability.
This driver's benefits are most readily seen on a platform
such as the SunFire X4500 (aka Thumper) where 6 Marvell 88SX6081
controllers, each on its own PCI bus, are connected to
a disk array of 48 SATA disks. Each disk is 500GB giving
a total capacity of 24TB and a combined disk I/O throughput
of 3.2GB/sec.
When Sun's new file system, ZFS is used on the platform, the
combined system gives a remarkable combination of performance,
reliability, availability and capacity.
