Guest Nikhil Posted February 13, 2008 Posted February 13, 2008 Hello, Does any version of Windows (e.g Longhorn, Windows XP etc) supports lun number greater than 255? Can windows see more than 256 luns? Thanks.
Guest Edwin vMierlo [MVP] Posted February 15, 2008 Posted February 15, 2008 Re: Lun number greater than 255 not sure about Windows 2008, but will post back later on that. Windows (2003) can see from LUN 0 to LUN 255 per target If you have a SAN, the zone in your HBA to another target and yet again you can see LUN 0 to LUN 255 (we are now up to 512) Repeat this, and you can have 16 targets per bus (bus being the HBA) (now we are up to 4096 LUNS) Add in a second HBA, and now we are on 8192 disks Obviously when those numbers get really big there is a lot of other considerations, not just LUN addressing So, 256 LUNs per target, but you are not limited on targets hope this helps Rgds, Edwin.
