Dell Technologies PowerEdge RAID
Controller 11
Dell Technologies PowerEdge RAID Controller 11, or PERC 11 is a series of RAID disk array controllers made by Dell for its
PowerEdge servers. The PERC 11 series consists of the PERC H755 adapter, PERC H755 front SAS, and PERC H755N front
NVMe cards which have the following characteristics:
● Provides reliability, high performance, and fault-tolerant disk subsystem management
● Offers RAID control capabilities including support for RAID levels 0, 1, 5, 6, 10, 50, 60
● Complies with Serial Attached SCSI (SAS) 3.0 providing up to 12 Gb/sec throughput
● Supports Dell-qualified Serial Attached SCSI (SAS), SATA hard drives, Solid State Drive (SSD), and PCIe SSD (NVMe)
● Supported drive speeds for NVMe drives are 8 GT/s and 16 GT/s at maximum x2 lane width.
NOTE: Mixing disks of different speed (7,200 RPM, 11,000 RPM, or 15,000 rpm) and bandwidth (3 Gbps, 6 Gbps, or 12
Gbps) while maintaining the same drive type (SAS or SATA) and technology (HDD or SSD) is supported.
NOTE: Mixing SAS, SATA, and NVMe drives in a virtual disk is not supported, and mixing HDD and SSD in a virtual disk is
not supported.
NOTE: For the safety, regulatory, and ergonomic information that is associated with these devices, and for more
information about the Integrated Dell Remote Access Controller (iDRAC) or Lifecycle Controller (LC) remote management,
see your platform documentation.
