The firmware source code is available on the Dell website, [18] but it is not possible to compile the source into a replacement firmware as Dell does not include a build environment. [19] The DRAC provides remote access to the system console (keyboard and screen) allowing the system BIOS to be accessed over the Internet when the server is rebooted.
Using a standardized interface and protocol allows systems-management software based on IPMI to manage multiple, disparate servers. As a message-based, hardware-level interface specification, IPMI operates independently of the operating system (OS) to allow administrators to manage a system remotely in the absence of an operating system or of the system management software.
dmidecode is a free userspace command-line utility for Linux that can parse the SMBIOS data. [2] [3] The name dmidecode is derived from Desktop Management Interface, a related standard with which dmidecode originally interfaced.
Devices like Dell DRAC also have a slot for a memory card where an administrator may keep server-related information independently from the main hard drive. The remote system can be accessed either through an SSH command-line interface, specialized client software, or through various web-browser-based solutions. [4]
In June 2013, Dell introduced the PowerEdge VRTX, which is a smaller blade system that shares modules with the M1000e. The blade servers, although following the traditional naming strategy e.g. M520, M620 (only blades supported) are not interchangeable between the VRTX and the M1000e. The blades differ in firmware and mezzanine connectors.
Dell uses the name PowerEdge RAID Controller (PERC) for proprietary versions of its RAID computer storage controllers. [16] The related software in the PERC Fault Management Suite offered facilities such as the Background Patrol read, which aims to fix bad sectors on online RAID disks running under some of the PERC controllers around 2006.

The vast majority of Intel server chips of the Xeon E3, Xeon E5, and Xeon E7 product lines support VT-d. The first—and least powerful—Xeon to support VT-d was the E5502 launched Q1'09 with two cores at 1.86 GHz on a 45 nm process. [2]
RDMA supports zero-copy networking by enabling the network adapter to transfer data from the wire directly to application memory or from application memory directly to the wire, eliminating the need to copy data between application memory and the data buffers in the operating system.
