      HPE Smart Array P542D Controller

      The HPE Smart Array P542D Controller is a PCI-Express (PCIe) 3.0 mezzanine, 4-port, 12Gb/s Serial Attached SCSI (SAS) RAID controller that supports internal and direct attached storage composed with HPE Synergy Compute Modules. It provides enterpriselevel reliability, connectivity, and performance for HPE Synergy compute and storage modules through its support of the latest SCSI technology and advanced RAID capabilities. The controller supports 2GB flash-backed write cache (FBWC) to maximize data retention in case of a power failure. It features eight external physical links and eight internal physical links within four ports to deliver increased compute module uptime by providing advanced storage functionality, including online RAID level migration with FBWC, global online spare, and pre-failure alert. With the addition of the HPE Synergy D3940 Storage Module and HPE Synergy 12Gb SAS Connection Module, a logical JBOD can be assigned to a Synergy Compute Module.
