This morning we have just taken delivery of our third EqualLogic PS Series array. A PS6000 with 32TB of storage, this new addition to our SAN infrastructure is going to be a replication partner to our existing EqualLogic group. I am going to be blogging about this replication project as I get going with it but firstly thought I would take the opportunity go through deploying a PS Array step by step straight out of the box and creating a new group.
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.
