RE: Preferred Disk Config

Title: Message

going from 3 to 4 drives is a significant boost in RAID 5 and it a drive dies the resulting changes will be minor compared to going to two disk. In test systems I have seen the exchange system shutdown for 35 minutes when a disk died with only a three disk with a  15 gig store.  The same system was down less then 2 minutes when a fourth disk was added then taken away, -----Original Message----- From: Martin Blackstone [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 26, 2001 8:36 AM To: MS-Exchange Admin Issues Subject: RE: Preferred Disk Config I would get 4 drives for the IS. There seems to be a great performance boost going from 3 to 4 drives in RAID 5. -----Original Message----- From: Colin Maynard [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 26, 2001 2:37 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 List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
