I know SAN != "mirrored RAID," but 20TB of commodity disks is ~$1600 (going by the price of the first 1TB drive I saw on Newegg.) As the very next post to yours says, "That entire post can be summarized as, "I do not know the concept of 'false economy'.""How much time is spent every day by users deleting old mail to keep under the limit? At the last place I worked at that was dumb enough to have quotas, I probably spent 10-20 minutes every week prioritizing what I felt I could live without.
Most businesses needing a 20TB SAN aren't going to be using using off-the-shelf stuff from Newegg, I just burned $15k on a 24TB storage array for 50 users. Still, storage can be cheap for media but there are a lot of other costs involved in adding that storage. I just finally got the greenlight to upgrade our ancient MS Exchange server and here are some of the financial implications of this process:
- Server old, larger drives are much more expensive than current tech so we replace server
- New server has more than 4GB of RAM so we upgrade to 64-bit O/S
- Old Exchange is no-go on 64-bit O/S so we upgrade Exchange
- This takes time, which as the only IT person for a company with heavy IT needs I do not have for such a large project, so we hire consultant to do it
So for us it's not as easy as just slapping in new drives and losing the quotas, just because some people are too f'n lazy to cleanup all the chain emails and Facebook notification spam from their mailboxes.
