Compact Flash Drive
The Sun Blade X6250 is equipped with a compact flash device that can support some
operating systems. It is the only local option for installing an operating system.
The following operating systems support booting from compact flash:
■
Solaris 10 8/07 Operating System U4 (64-bit) or later
■
Red Hat Enterprise Linux 4.6 (32/64-bit) or later
■
Red Hat Enterprise Linux 5.0 (64-bit) or later
■
SUSE Linux Enterprise Server 9 Sp4 (64-bit)
■
SUSE Linux Enterprise Server 10 Sp1 (64-bit) or later
■
VMware ESX 3.0.2+
■
Windows 2003 32-bit and 64-bit
■
Windows 2008 32-bit and 64-bit
The compact flash drive supports a finite number of writes before its performance
degrades. You can mitigate the limited number of writes by configuring it to redirect
the log files (the
/var
and
/tmp
directories) to another location. See your operating
system documentation for details.
Solid State Disk Drive (SSD)
The X6250 server module supports installing SSDs in the HDD bays. Each SSD
provides 32Gb of SATA capacity.
The following conditions apply:
■
SSDs cannot be combined with any other drive, SATA or SAS.
■
SSDs can only be connected through the onboard SATA connection.
Connecting to SAS Devices
The SAS-NEM module, mounted in the back of the chassis, allows to the Sun Blade
X6250 Server Module to connect to SAS devices inside the chassis and outside of the
chassis. Each chassis can support one or two SAS-NEM modules.
These configurations require the Sun Blade X6250 Server Module to have either a
REM or a FEM.
■
Inside the chassis
, the Sun Blade 6000 Disk Module provides eight SAS drives.
