1U Server; Maximize I/O with Eight NVMe
This 1U PowerEdge R640 configuration offers up to eight NVMe drives and two
SAS/SATA drives. The first eight NVMe drives connect directly to CPU2 and the last
two SATA/SAS drives are connected to CPU1 through the MB mini-PERC. This
configuration supports a great deal of NVMe capacity and allows for all I/O slots to
remain available for other functional purposes.
