Which version of Exchange? I'm currently planning our move from 2003 to 2010 and really you want to run Jetstress to ensure you get the IOPS you want within acceptable latency etc.

Ok, if it helps, we're using iSCSI over Ethernet, on 1 Gbps connections, with about 900 users -----Original Message----- From: Ken Schaefer [mailto:[email protected]] Sent: Monday, March 14, 2011 9:00 AM To: NT System Admin Issues Subject: RE: Exchange Database -- VMDK or RAW? Without knowing the parameters of your environment, this isn't really that useful. E.g. if you are using iSCSI over Ethernet, then it makes a big difference if you are using 1gbps vs 10gbps (depending on the environment size). If you only have 100 users, it doesn't matter if you are using VMDK vs RAW and iSCSI vs FC. If you have 100,000 users, it does.

We use the MS iSCSI initiator to attach all the Exchange data and log drives. There have been no observable performance issues doing so in our environment. Use Dell's "extpart.exe" for 2003, or the W2008 native "diskpart", we've been able to grow the drives on the fly when we needed to add space for some reason. I know you can do the same with VMDK files, but don't have any experience with RAW drives. -----Original Message----- From: Jon D [mailto:[email protected]] Sent: Monday, March 14, 2011 8:31 AM To: NT System Admin Issues Subject: Exchange Database -- VMDK or RAW? For those who have your Exchange boxes inside of VMWare, did you put your databases inside VMDK files, or did you go RAW? VMDK seems like it would be easier to manage, but I'm wondering about size issues, performance, etc. Thanks, Jon ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin -- MIRA Ltd Watling Street, Nuneaton, Warwickshire, CV10 0TU, England Registered in England and Wales No. 402570 VAT Registration GB 100 1464 84 The contents of this e-mail are confidential and are solely for the use of the intended recipient.
