Dell PowerEdge RAID Controller H710 - Manual (Page 9)

Overview
The Dell PowerEdge RAID Controller (PERC) H310, H710, H710P, and H810 family of storage controller cards has the
following characteristics:
• Complies with serial-attached SCSI (SAS) 2.0 providing up to 6 Gb/sec throughput.
• Supports Dell-qualified serial-attached SCSI (SAS) hard drives, SATA hard drives, and solid-state drives (SSDs).
NOTE: Mixing SAS and SATA drives within a virtual disk is not supported. Also, mixing hard drives and
SSDs within a virtual disk is not supported.
NOTE: Mixing disks of different speeds (7,200 rpm, 10,000 rpm, or 15,000 rpm) and bandwidth (3 Gbps or 6
Gbps) PCIe while maintaining the same drive type (SAS or SATA) and technology (HDD or SSD) is
supported.
• Offers RAID control capabilities which include support for RAID levels 0, 1, 5, 6, 10, 50, and 60.
NOTE: PERC H310 supports RAID 5 with limited performance and does not support RAID 6 and RAID 60.
• Provides reliability, high performance, and fault-tolerant disk subsystem management.
• Offers Non-RAID support for direct access to disk drives (PERC H310 only).
NOTE: Operating systems can directly access Non-RAID hard drives. A Non-RAID hard drive is not fault-
tolerant and cannot be recovered if it fails. Only the PERC H310 controller allows configuration of disk
drives as Non-RAID.
The following table compares the hardware configurations for the PERC H310, H710, H710P, and H810 cards.
