A quick start wizard steps through configuring the four iSCSI data ports and choosing spare drives to cover any failures.
Your next task is to create RAID groups where you choose your drives and decide on an array type which can range from a simple mirror to dual drive redundant RAID 6. The process is very simple as you choose either SAS or SATA drive types, pick an array and decide how many drives are to be used in it.
Target creation is a swift process as you create a logical unit, decide on its size in MB, GB, TB or blocks and choose a LUN (logical unit number). You can assign it to a specific data port and either use an existing iSCSI target or create a new one. Access security is good as it can be enabled on individual data ports to stop more than one host logging in to an iSCSI target and you can implement CHAP authentication as well.
The GS2040 returned some good results in our performance tests. Starting with a Dell PowerEdge R515 running Windows Server 2008 R2 64-bit, we saw the Iometer utility report high raw read and write throughputs of 110MB/s and 100MB/s.
We then connected a Broadberry dual Xeon X5560 rack server to a data port on the second controller and logged it into a dedicated iSCSI target. With Iometer running on both systems we saw a cumulative raw read throughput of 220MB/s showing no contention for resources was occurring.
