A.3 Upgrading or Replacing Memory Your DSN-1100 storage system supports up to 1 GB of buffer(cache) memory and 512 MB of system memory using a total of two Dual In-line Memory Module (DIMM) sockets on the DSN1100 storage system Controller:  One DIMM sockets (J14) is for buffer (cache) memory.  One DIMM socket (J15) is for system memory. System Memory: The xStack Storage controller can address up to 512MB of system memory. Your controller comes standard with 256MB (1 x 256MB module). Please see Figures A-10 and A-12 for the system memory location. Buffer (Cache) Memory: The xStack Storage controller can address up to 1GB of buffer memory, and comes standard with 256MB (1 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 Figures A-10 and A-11 for buffer memory location. Note on Memory: Table A-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 support.dlink.com website for tested memory modules. Table A-2 shows the possible memory configurations for your xStack Storage controller. System Memory Rear of Chassis Figure A-10.
