Now that our new Dell EqualLogic PS6000 is racked, networked, initialized and configured it’s time to bring the firmware version up-to-date. Currently the newest firmware version is V5.0.7 and can be downloaded from EqualLogic Support.
Updating the firmware is a fairly simple task, a PS Series Array has dual controllers each with a micro SD card inserted on the underside of the controller (the opposite side to the fan) this is where the firmware runs from.
Most of the time you can update directly to the latest firmware version, it maybe that you need to update to an interim version before updating to the latest version, it really depends on how far behind you are. Always read the firmware release notes.
Following on from my Hyper-V Post I thought I would carry on the theme of High Availability and clustered services. Dell's EqualLogic PS Series iSCSI SAN optimise's resources by automating volume and network load balancing. A PS Series Group consists of one or more PS Series Array. Group Members are connected to an IP network and managed as a single system.
iSCSI or internet small computer systems interface to give it its full title, is a block level storage protocol that can be used to create a storage network over Ethernet. iSCSI uses ethernet as a transport medium for data from servers to storage devices or SAN'S (Storage Area Networks) such as EqualLogic. iSCSI encapsulates SCSI commands into TCP/IP and sends these commands over standard Ethernet, because of this iSCSI can be sent over LAN's and WAN's and these Arrays do not have to be located in the same room or even the same Galaxy as your servers.
