A poorly configured server with 16 disks can perform worse than a server with only six disks. However, special attention needs to be paid to the applications that are being hosted by an NFS server. You can tune RAID arrays to serve many smaller files quickly, or they can be configured to serve many larger files quickly. Reliability is a key factor for NFS file servers. Besides assisting in the speed department, RAID can replicate information in times of single-drive failures.
Most servers can detect a bad drive and automat ically switch to a drive marked as a hot spare.
Its ability to prevent downtime is unparalleled. SFT stands for symmetric fault tolerance. This is critical to the device's ability to maximize uptime while minimizing effort. Betty informs the couple's shared hardware RAID controller that Adam is not working, and she will now be ser ving Adam's file systems. Betty then serves Adam's file systems until Adam is revived.
