iSCSI

iSCSI (internet SCSI) is a standard that implements the SCSI protocol for interacting with storage
devices over a TCP/IP network. While iSCSI can be implemented over any TCP/IP network, the most
common implementation is over gigabit Ethernet. iSCSI serves the same purpose as Fibre Channel in
building Storage Area Networks (SANs), but without the cost, complexity, and compatibility issues
associated with Fibre Channel SANs.
In iSCSI terminology, initiators are devices that access storage resources through the iSCSI protocol. A
target is the device that the initiator accesses. While the target is usually a hard drive enclosure or
another computer, it can also be any other storage device that supports the iSCSI protocol, such as a
tape drive.
Initiators can be divided into two categories: software initiators and Host Bus Adapters (HBAs).
Software initiators implement the iSCSI protocol in software, and CPU resources are used to manage
the protocol stack. A more efficient approach is to offload the management of the protocol to the
network adapter. Adapters that implement the iSCSI protocol are known as iSCSI HBAs. These
devices appear to the operating system to be a SCSI HBA. The NC371i is an iSCSI HBA and
appears to the operating system as a SCSI HBA.

Management technologies

HP ProLiant servers are shipped with management technologies that include Integrated Lights-Out 2
and the ProLiant Essentials Foundation Pack.

Integrated Lights-Out 2

Integrated Lights-Out 2 (iLO 2) is the fourth generation of Lights-Out remote management for HP
servers. iLO 2 is hardware and firmware integrated into most ProLiant servers. It provides remote
management capabilities over Ethernet. iLO 2 is most useful in situations that require remote server
management. It is active even when the OS is not operating. The iLO 2 management processor
obtains its power from the auxiliary power plane of the server, so it is always available when the
server is plugged into a power source.
There are three levels of licensing for iLO 2: iLO 2 Standard, iLO 2 Select Packs, and iLO 2
Advanced Packs. Each offers different levels of remote access capabilities.
The DL585 G2 can connect to iLO 2 through a dedicated Ethernet port. This port can connect to a
dedicated management network that is out of the server's data path and that can be highly secured.
On DL585 G2 servers, iLO 2 can assign an additional MAC and IP address to one of the standard
embedded network interfaces and share that port with normal traffic. This shared arrangement
eliminates the need for an extra network connection for iLO 2.
For more information about iLO 2, refer to the HP technology brief titled "Integrated Lights-Out
technology: enhancing the manageability of ProLiant servers."4
