I don't see the point in have Raid 1 and Raid 5 in the same system.. There is no data on the system to protect.. Raid 0+1 would better if you already have the equipment. -----Original Message----- From: Adam_Baum@xxxxxxxxxxxxx [mailto:Adam_Baum@xxxxxxxxxxxxx] Sent: Friday, July 12, 2002 8:40 AM To: thin@xxxxxxxxxxxxx Cc: 'thin@xxxxxxxxxxxxx'; thin-bounce@xxxxxxxxxxxxx Subject: [THIN] Re: What is the optimal RAID configuration One thing no one has asked yet (at least I have not seen it), is how are the two different RAIDs going to be configured? The original question stated RAID1 for system, RAID 5 for application. Is this all happening on the same system? If so, unless this server has the ability to split the drive cage into multiple channels, there will be a performance hit mixing the two styles. I tried this on a DL580 and DL380 and was very disappointed with the results. adam Joe Shonk <JShonk@gtcsyst To: "'thin@xxxxxxxxxxxxx'" <thin@xxxxxxxxxxxxx> ems.com> cc: Sent by: Subject: [THIN] Re: What is the optimal RAID configuration thin-bounce@fre elists.org 07/12/2002 08:39 AM Please respond to thin RAID 1 is fault-tolerant... Multiple load balanced servers in a farm are not. Granted there is contigencies/redundancy built in a load balanced farm, but it's not considered fault-tolerant. If the drive fails, the whole server fails. Dropping any connections it had with it, and possible loss of valuable data. With Raid 1, if you lose a drive your still ticking aways as if nothing happened. -----Original Message----- From: Roger Riggins [mailto:Roger@xxxxxxxxxxxx] Sent: Friday, July 12, 2002 8:13 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: What is the optimal RAID configuration Another possibility is RAID 0 if you want performance, let multiple servers be your redundancy.

Since your applications are running from another server (hoepully) then the additional RAID 5 configuration is unnecessary. Most of the people that I work with are using 1U servers for Metaframe, so supporting a RAID 5 array is impossible within the server itself. -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Sangha, Jay S Sent: Friday, July 12, 2002 7:36 AM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] What is the optimal RAID configuration Does anybody have any information in regards to optimal disk RAID configuration for WTS/Citrix servers. We are putting together a new build standard but we are unsure as to the best set-up. We are considering RAID 1 for the system and RAID 5 for the application. Is this sort of stuff documented anywhere.
