6 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
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 D ell.com/PERC.
