Rik, I believe in your case it's going to be all about the speed of the drives. I'm not sure that even 8 10k rpm drives configured with stripe/parity will achieve this in a standard environment. The bigger question isn't the speed of the writes but rather the delta changes per second to the database. -----Original Message----- From: drbd-user-bounces at lists.linbit.com on behalf of Rik Herrin Sent: Thu 3/9/2006 3:06 AM To: drbd-user at lists.linbit.com Subject: [DRBD-user] Anyone Get Write Speeds over 150MB/s Writes using DRBD? Hi, I am currently evaluating the use of drbd for real-time replication of an Oracle DB. The hardware that the Oracle DB will be running on involves 2 dual-core AMD Opterons, 4 GB RAM, an LSI MegaRAID 320-2X SCSI RAID Controller with 512MB NVRAM, and 10k SCSI Hard drives (8 of them). An Intel Pro/1000 MT Quad Pro Server Adapter card will be used for networking, with 2 ports dedicated to the DRBD connection to a similarly configured machine. Would drbd be a bottleneck in this configuration? The NIC should be able to deliver about 180MB/s or so and so should the SCSI RAID controller. Anyone have experience with this type of hardware? Thank you for your time. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
