https://community.hpe.com/t5/disk-enclosures/striping-size/m-p/2543673#M2116 I'm setting up Exchange 5.5 on a Compaq Proliant ML530 server. I have created 3 Arrays (operating system RAID1, logs RAID1, Exchange database RAID5). <BR />I am wondering about the best Striping Size (Smart Controller) and Allocation Unit Size (Operating Sistem). <BR />I've read that the best performance should be with the largest striping size and an Allocation Unit Size matching the size of I/O operations (depending on the application). Is this correct? <BR />- What is the best striping size for a RAID 5 Array? <BR />- What is the best Allocation Unit size for Exchange 5.5 Log partition and Exchange 5.5 databases? <BR /> <BR />Thanks in advance <BR />Frigo Positivo Thu, 21 Jun 2001 23:00:00 GMT Ayman Altounji 2001-06-21T23:00:00Z https://community.hpe.com/t5/disk-enclosures/striping-size/m-p/2543673#M2116 I'm setting up Exchange 5.5 on a Compaq Proliant ML530 server.
