Hardware Considerations

  Asked By: Domonique    Date: Mar 11    Category: MOSS    Views: 514

We are getting ready to order hardware for our new SharePoint MOSS 2007
deployment. We are going with a (5) server configuration of (2)wfe, (1) index
and (2)clustered SQL servers.

Can someone volunteer their thoughts on RPMs versus disk size for the WFE and
INDEX servers? If we go with 15,00RPM drives we are limited in size where a
10,000 offers larger disk options.

My concern is with the index file created by the INDEX server. Should we also be
thinking that it should be replicated to both WFE or just one?

Your query roles should go on the WFE, so you'll be replicating the full text
index on both WFE and it will also be held on the Index server. Your SSP Search
database that holds the metadata for the index will be at least 2x size  of your
index in most cases. For example, if you crawl 1TB of data, your index might be
100GB, but your search database could be anywhere from 200 - 300 GB. FYI

It's your SQL server  you need to be concerned with, not your index/query

So, you don't think the size  is such an issue to consider on the INDEX server?
So, it looks like we will go with the faster but smaller drives  on the WFE(s)
and INDEX server. [15K RPM drives under RAID 10.] I believe we are initially
building to hold 1TB of data on the SQL servers.

What you first need to do is an inventory of the data you wish to index, get
approx. sizes of that data, then scale your disk  space topology accordingly. Be
sure to purchase enough disk space to keep up with the data growth rates in your
organization. It's much easier to get more disk space now than to go back later
and ask for more because you under-sized your servers. Managers don't like to
be nickel-n-dimed.

Doing an inventory of your data will also help reveal what data is old,
outdated, trivial and/or redundant. Deleting such data can help achieve better
use of the disk space that you do purchase.
