Storage

The PowerEdge R920 supports extensive internal and external storage options. Support for internal

storage includes a number of variations with a 2.5” drive chassis. For external storage, there are a

number of storage options that range from JBOD connectivity to SAN support with Dell Compellent.

Connectivity options include: host bus adaptors (HBA) options for SAS, iSCSI and Fibre Channel.

New server storage features such as Express Flash NVMe PCIe SSDs and software caching solutions

provide accelerated application/workload performance over previous technologies. Express Flash

drives use PCIe bus lanes to connect directly to the processor and chipset and are easily accessible

through the hot-plug drive bay.

Dell PowerEdge Express Flash NVMe PCIe SSDs

The PowerEdge R920 supports up to eight PowerEdge Express Flash NVMe PCIe SSDs, high-

performance storage devices designed for solutions requiring ultra-low latency, high input/output

operations per second (IOPs) and enterprise-class storage reliability and serviceability. With a choice

of 400GB, 800GB and 1.6TB capacities, PowerEdge Express Flash NVMe PCIe SSDs interact with and

optimize high-performance NAND, achieving ultra-high IOPs and sequential read/write speeds.

Express Flash NVMe PCIe SSDs deliver exceptional performance in demanding enterprise

environments, such as blade and enterprise servers, online transactional processing (OLTP)

databases, video-on-demand servers, web accelerators and virtualization workloads.

Supported RAID controllers

The newest line of PowerEdge RAID Controller (PERC) cards offers high I/O performance for

database applications and streaming digital media environments. Internal RAID controllers have a

dedicated connection to the motherboard. The R920 supports the new PERC 8 family of controllers

with improved functionality and faster performance.

The R920 supports the PERC cards listed in Table 10. For more information about the latest PERC

offerings, see Dell.com/PERC.
