SQL Server 2005 & 2008 on a Cluster in Production

Lorisj33 — Tue, 17 Aug 2010 14:46:46 +0000

Is it acceptable to run SQL 2005 and SQL 2008 side-by-side on the same MS cluster (single-instance) cluster in production? At least temporarily until all SQL 2005 DB appl vendors are approved on SQL 2008. I know there were issues and recommendations to Not do this with SQL 2000 and 2005 because they were so different. Any issues we need to know about whether it be in general or relating to the cluster?

Upgrade SQL 2005 Cluster to SQL 2008

tcstl — Thu, 05 Aug 2010 17:48:43 +0000

We have a remote sql 2005 server set we will be replacing with a Windows 2008 Cluster. The db supports a 3rd party app. The app has not completely endorsed for sql 2008. If I build an active/passive cluster with sql 2005 on Windows 2008, is there the ability to upgrade the sql server to a SQL 2008 cluster without rebuilding the Win2008 OS

SQL Server 2005: Improving performance of Multiple Databases & LUNS

Bulldog98 — Sat, 19 Jun 2010 17:25:24 +0000

I am looking at ways to improve performance of our databases. We have 4 large databases (ranging between 50gb and 200gb each) on a single SQL Server 2005 Cluster. Currently they are split 2 on one LUN and 2 on another. I am looking at ways to improve the IO performance of the databases as they are quite IO intensive. I have been investigating options to create 6 LUN’s and reduce the number of MDF files for each database from 8 to 6 and then spreading the MDF’s across all 6 LUN volumes. Currently we have 16 disks for LUN1 in RAID 10 and 16 disks for LUN2 RAID 10. If I proceed with the changes I am investigating then we would have 6 LUNS with 6 disks each in RAID 10. 1 data file per a database will sit on each LUN. Should this improve performance? does anyone have experience in this area that they could share?

How many tempdb’s necessary in our clustered environment?

SQL Server Ask the Experts — Mon, 09 Mar 2009 18:18:42 +0000

We have a clustered environment with three nodes and five instances. Each node has eight CPU’s, and we are wondering how many tempdb’s are necessary for each instance. Do you do the calculation on the total number of CPU’s, all 5 instances failed over to one node or some other variation that I should be considering?
