RE: Preferred Disk Config

Title: SMTP mail to exchange help

If money is not an issue, I would go with:   2 x 9 GB RAID 1 for system 2 x 18 GB RAID 1 for transaction logs 6 x 36 GB RAID 0+1 for Database   RAID-5 is fine, but if you ever need to restore a database it might take 5 times longer to write.  Writes are awfully slow on RAID-5, and 0+1 will have an edge on all areas of performance with the protection of mirroring.  If you got the money, go with 0+1, to save money use RAID-5.   We have a RAID-5 subsystem on one server.  I had to do a recovery on it, because Dell had a bug in the Perc controller, corrupting the database.  After it was fixed, I did a restore, and it took 4 hours for a 10 GB priv.  I did the same store on a Compaq running a 5300 controller and 0+1, the restore took 30 minutes.   -----Original Message----- From: Colin Maynard [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 26, 2001 5:37 AM To: MS-Exchange Admin Issues Subject: Preferred Disk Config   Hi All,   I know that this question has been asked before so I apologise in advance but can't seem to find a solid answer anywhere.  Here goes.   What would be the ideal disk config for performance and reliability?  Money is not an issue at this time. I am thinking:   2 x 9Gb RAID 1 for System 2 x 18Gb RAID 1 for transaction logs 3 x 36Gb RAID 5 for Info stores   Please let me know if I have got it completely wrong as I need to recommend a solution soon and would rather get it right first time :-)   TIA   Colin   List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
