Value 1U Server that Supports up to Four NVMe Drives
The 1U PowerEdge R440 server offers up to four NVMe drives and six Serial-Attached
SCSI (SAS) or Serial Advanced Technology Attachment (SATA) drives. The first six
SATA/SAS drives are connected to the motherboard (MB) through an embedded
PowerEdge Raid Controller (PERC). The first two NVMe drives are connected through
to the CPU1 PCIe slot through a PCIe extender card which enables the PCIe lanes from
the PCIe slots to be cabled to the backplane for NVMe support. The last two NVMe
drives connect directly to CPU2. This value server can offer either less NVMe capacity,
with two NVMe drives, or more NVMe capacity, with four NVMe drives, where the 3
rd
and 4
th
drives connect through a PCIe bridge card in an I/O slot.
