D.2 Installing Memory The xStack Storage Array provides four memory sockets: Two sockets (J36 and J37) are for buffer memory Two sockets (J38 and J39) are for system memory System Memory: The xStack Storage controller can address up to 2GB of system memory, but only 512MB are required for operation of your controller. Your controller will have come standard with at least 512MB (2 x 256MB modules) making upgrading of system memory not necessary. Please see Figure D-6 system memory location. Buffer (Cache) Memory: The xStack Storage controller can address up to 2GB of buffer memory, and comes standard with at least 512MB (2 x 256MB modules) installed. This should work well for most applications. However, several applications (such as video streaming) of the product could benefit from increased cache memory. Please see Figure D-6 for buffer memory location.Note on Memory: The xStack Storage controller's system and buffer memory must be installed as matching pairs. Table D-1 lists the specifications for DIMMs supported by the xStack Storage Array. These memory module specifications are crucial to the operation of your SAN array. Please visit the www.dlink.com website for tested memory modules. Table D-2 shows the possible memory configurations for your xStack Storage controller. Please note that you must use matching memory modules for DIMM0 & DIMM1 as well as matching memory modules for DIMM2 & DIMM3.

D.2
Installing Memory
The xStack Storage Array provides four memory sockets:
°
Two sockets (
J36
and
J37
) are for buffer memory
°
Two sockets (
J38
and
J39
) are for system memory
System Memory
: The xStack Storage controller can address up to 2GB of system memory, but
only 512MB are required for operation of your controller.
Your controller will have come
standard with at least 512MB (2 x 256MB modules) making upgrading of system memory not
necessary.
Please see Figure D-6 system memory location.
Buffer (Cache) Memory
:
The xStack Storage controller can address up to 2GB of buffer
memory, and comes standard with at least 512MB (2 x 256MB modules) installed.
This should
work well for most applications.
However, several applications (such as video streaming) of
the product could benefit from increased cache memory.
Please see Figure D-6 for buffer
memory location.Note on Memory:
The xStack Storage controller’s system and buffer memory
must be installed as matching pairs.
Table D-1 lists the specifications for DIMMs supported by
the xStack Storage Array.
These memory module specifications are crucial to the operation of
your SAN array.
Please visit the
www.dlink.com
website for tested memory modules.
Table D-2 shows the possible memory configurations for your xStack Storage controller.
Please note that you must use matching memory modules for DIMM0 & DIMM1 as well as
matching memory modules for DIMM2 & DIMM3.
