Sorry for the off-topic question but I need advice on a buying a ISCSI SAN for 4-6 servers running CentOS 4.4 .The main purpose for the SAN is to store email accounts (that will be accessed by imap - dovecot) and other documents. Minimal redundancy is required (e.g. dual power supplies, battery backed write cache or mirrored controllers) and price for a 2 TB configuration should be under $ 10000. Right now the short list includes Promise VTrack M300i and Dell/EMC AX150i. Do you have any experience with any of these models or can recommend a similar SAN that will meet the above requirements?
I have bad experience of the Promise M500i.. loosing configuration on reboot, whole array crashing when one drive fails, locking problems crashing the UI (or blocking the use of it), general feeling of being extremely version 0.0.1.
I have been using Equallogic PS-series arrays, and they are excellent: fast, easy to use, stable, reliable and Equallogic has great support.. Promise has really sucky support (based on my experiences). But of course the price tag of Equallogic is something different compared to Promise.. You get what you pay for..
If you wanna play with DIY solutions try Linux iSCSI Enterprise Target.. and maybe openfiler.
