I run quite a few production servers on CF drives in a very large (12k+ servers) data center environment. In nearly every case, the CF card is the systems root (/) partition and is always mounted read-only. In some cases where we use CF, the systems also have a SAS/SATA disk for maintenance. When needed, we can spin up the SAS/SATA disk. On that hard drive, we keep a history of the CF card images and other maintenance items like /usr/ports and /usr/src. We use ATA CF adapters that I buy off eBay for $1.98 each. They ship direct from Hong Kong and work great.Received on Sun Dec 16 2007 - 19:09:54 UTC
