Effectively up to 12GB of write cache is provided using compression of 4 GB of physical cache. The #EJ0L provides four Mini-SAS HD (high density) narrow connectors for the attachment of SAS drives located in the SAS EXP24S expansion drawer or#5802/5803/EL36 12X PCIe I/O drawers. X, YO or AT SAS cables with HD narrow connectors are used to attach to these drawers. A max of 4 EXP24S can be attached with a maximum of 96 HDD or a maximum of 48 SSD. If controlling drives in a #5802/5803/ EL36 at least one of he #EJ0L pairs must be located in that #5802/ 5803/EL36. Two AA SAS cable with HD narrow connectors are attached to the #EJ0L pair to communicate status and cache content information and are required unless three or four ports are being used to attach HDD/SSD.
