Pagefile on a separate hard drive, what happens if that drive fails?
Posted on 2006-06-30
I have a PowerEdge 2500 with a PERC3/Di RAID controller with 3x 9.1GB HD and 3x18.4GB HD and will be installing Small Business Server 2003.
There are a lot of people that recommends using a RAID1 for the OS and a RAID5 for the data and also many people recommends having the pagefile on a separate hard drive to improve the performance, they also recommend to not use fault tolerant arrays for the pagefile as it will impact on the performance.
Based on those suggestions and my config I tought using 2x 9.1GB on a RAID1 for the OS, 3x 18.4GB on a RAID5 for data and the remaining 9.1GB as a simple HD for the pagefile.
Then, this is my question: What happens if the pagefile HD fails, will the OS crash? what is the point of having RAID1 on the OS if the server will go down with the pagefile... will it be a better solution to put the pagefile inside the OS array and leave the that HDD as a hot spare? in this case, is 9.1GB to little for a Small Business Server installation including the pagefile?
Thanks all in advance for any suggestion.
