Disk Multiplexing - Spreading disk drives over multiple disk
controllers using RAID 1 and 5 (hardware RAID). This prevents data access
loss due to controller hardware. Disk Multiplexing is transparent to the
computer Operating System. Therefore, it can contain the SYSTEM and BOOT
partitions.
Software implementations of RAID (no disk multiplexing) require drivers in
order to operate. This prevents some RAID volume types from containing
the SYSTEM and BOOT partitions (the driver must be loaded from these volumes).
RAID 0 - Disk Striping:
- 2 disk drives required.
- Can contain SYSTEM and BOOT partitions.
RAID 1 - Disk Mirroring:
- 2 disk drives required.
- Can contain SYSTEM and BOOT partitions.
- ftdisk.sys
RAID 5 - Disk Striping w/parity:
- 3 disk drives required.
- Slower disk writes (parity calculations)
- Fast disk reades (stripes) best with disk multiplexing
- Cannot contain SYSTEM and BOOT partitions (unless hardware RAID 5).
- Total available disk space = sum of volumes - 1 volume. 6 10mb volumes = 50mb available space.
When striping, the more hard disks used, the less expensive the parity
stripe.
Windows 2000 Partition Terminology:
SYSTEM Partition - The active boot partition which contains BOOT.INI.
BOOT Partition - The partition containing the system files "WINNT".

dynamic storage is configured as volumes, basic storage holds up to
4 primary partitions.
- simple volume
- spanned volumes - simple volume 1 + 2 = larger volume across disks.
- striped volumes - 0 - 0 - 0 - faster i/o (64kb stripes)
- mirrored volumes - 0 = 0 - mirroring = 1 controller, duplexing = 2 controllers.
- RAID-5 volumes - strip w/parity.
- extended volumes - adding disk space to a single simple volume.
You cannot created extended volumes from an basic to dynamic upgrade drive.
Laptop computers support only "basic storage" (no dynamic disks)
Windows 2000 Professional supports simple, spanned, and striped volumes.
You cannot specify a quota for a group, either all new users or for
individual users.
For hot-swapping, use Disk Management to Rescan Disk (action menu).
If dual booting with NT4.0, it requires SP4 for NTFS 5.0 support.
