CHAPTER 3: NVIDIA RAID FUNCTIONS
3.1 OPERA TION SYSTEM
Supports Windows XP Home/Professional Edition, and
Windows 2000 Professional.
3.2 RAID ARRAYS
NVRAID supports the following types of RAID arrays:
RAID 0: RAID 0 defines a disk striping scheme that improves
disk read and write times for many applications.
RAID 1: RAID 1 defines techniques for mirroring data.
RAID 0+1: RAID 0+1 combines the techniques used in RAID 0
and RAID 1.
RAID 5: RAID 5 provides fault tolerance and better utilization of
disk capacity.
Spanning (JBOD): JBOD provides a method for combining
drives of different sizes in to one large disk.
20
Us e r’s M anual
Page 23
Biostar T-Series TForce U 775
3.3 HOW RAIDWORKS
RAID 0:
The controller “stripes” data across multiple drives in a RAID 0
array system. It breaks up a large file into smaller blocks and
performs disk reads and writes across multiple drives in parallel.
The size of each block is determined by the stripe size
parameter, which you set during the creation of the RAID set
based on the system environment. This technique reduces
overall disk access time and offers high bandwidth.
Features and Benefits
Drives: Minimum 1, and maximum is up to 6 or 8. Depending on
the platf orm.
Uses: Intended for non-critical data requiring high data
throughput, or any environment that does not require fault
tolerance.
Benefits: prov ides increased data throughput, especially f or
large f iles. No capacity loss penalty for parity.
Drawbacks: Does not deliver any fault tolerance. If any drive in
the array f ails, all data is lost.
Fault Tolerance: No.

21
Data 2
Data 4
Data 6
Us e r’s M anual
Page 24
Biostar T-Series TForce U 775
RAID 1:
Every read and write is actually carried out in parallel across 2
disk drives in a RAID 1 array system. The mirrored (backup)
copy of the data can reside on the same disk or on a second
redundant drive in the array. RAID 1 provides a hot-standby
copy of data if the active volume or drive is corrupted or
becomes unavailable because of a hardware failure.
RAID techniques can be applied for high-availability solutions,
or as a form of automatic backup that eliminates tedious
manual backups to more expensive and less reliable media.
Features and Benefits
Drives: Minimum 2, and maximum is 2.
Uses: RAID 1 is ideal f or small databases or any other
application that requires f ault tolerance and minimal capacity.
Benefits: Prov ides 100% data redundancy. Should one driv e
f ail, the cont roller switches to the other driv e.
Drawbacks: Requires 2 driv es for the storage space of one
driv e. Performance is impaired during drive rebuilds.
Fault Tolerance: Yes.

RAID 0+1:
RAID 0 drives can be mirrored using RAID 1 techniques.
Resul tin g in a RAID 0+1 solution for im proved perfo rmance plus
resiliency.
Features and Benefits
- Drives: Minimum 4, and maximum is 6 or 8, depending on the
platform.
- Benefits: Optimizes for both fault tolerance and perf ormance,
allowing for automatic redundancy. May be simultaneously
used with other RAID levels in an array, and allows for spare
disks.
- Drawbacks: Requires twice the available disk space f or data
redundancy, the same as RAID level 1.
- Fault Tolerance: Yes.

Biostar T-Series TForce U 775
RAID 5:
RAID 5 stripes both data and parity information across three or
more drives. It writes data and parity blocks across all the
drives in the array. Fault tolerance is maintained by ensuring
that the parity information for any given block of data is placed
on a different drive from those used to store the data itself.
Features and Benefits
Drives: Minim um 3.
Uses: RAID 5 is recommended for transaction processing
and general purpose service.
Benefits: An ideal combination of good perf ormance, good
f ault tolerance, and high capacity and storage eff iciency.
Drawbacks: Individual block data transfer rate same as a
single disk. Write perf ormance can be CPU intensiv e.
Fault Tolerance: Yes.

Spanning (JBOD):
JBOD stands for “Just a Bunch of Disks”. Each drive is
accessed as if it were on a standard SCSI host bus adapter.
This is useful when a single drive configuration is needed, but it
offers no speed improvement or fault tolerance.
Features and Benefits
- Uses: J BOD works best if y ou hav e odd sized driv es and y ou
want to combine them to make one big driv e.
- Benefits: JBOD prov ides t he ability to combine odd size drives
using all of the capacity of the drives.
- Drawb acks: Decreas es perform ance because of the difficulty
in using drives concurrently.
- Fault Tolerance: No.

7 PnP/PCI Configurations
This section describes configuring the PCI bus system. PCI, or Personal Computer
Interconnect, is a system which allows I/O devices to operate at speeds nearing the sp eed of
the CPU its elf uses when co mmunicating with its own special co mponents. This secti on
covers some very technical items and it is strongly recommended that only experienced
users should make any c hange s to the defa ul t set tings.
Figure 7. PnP/PCI Configurations
Init Display First
With systems that have multiple video cards, this option determines whether the primary
display uses a PCI Slot or an AGP Slot.
The Choices: PCI Slot (default), AGP.
Reset Configuration Data
The system BIOS supports the PnP feature which requires the system to record which
resources are assi gned and protec ts resources from conflict. Ever y peripheral devic e has a
node, which i s call ed ESCD. This n ode r ecords which res ources are assi gned t o it. Th e
system needs to record and update ESCD to the memory locations. These locations (4K)
are reserved in the system BIOS . If the Disabled (d efault) option is chosen, the system‘s
ESCD will update only wh en th e new configuration varies fro m the la st on e. If the En abl ed
option is chosen, th e syst em is forc ed to up date ESCDs and then is auto matically set to th e
“Disabled” mode.
The above settings will be sho wn on the screen only if “Manual” is chos en for the resources
controlle d by functi o n.
Legacy is th e term , wh ich si gnifi es th at a r es ourc e is assi gn ed t o t he ISA B us and pro vid es
non-PnP ISA add-on cards. PCI / ISA PnP signifies that a resource is assigned to the PCI
Bus or provides fo r ISA PnP add-o n ca r ds and pe ripherals.
The Choices: Disabled (default), Enabled.

Resources Controlled By
By Choosing “Auto(ESCD)” (d efault), th e system BIOS will detect the s ystem resou rces
and automatically assign the relative IRQ and DMA channel for each peripheral.By
Choosing “Manual”, the user will need to assign IRQ & DMA for add-on cards. Be sure
that there are no IRQ /D MA and I/O por t co nfli ct s.
IRQ Resources
This submenu will allow you t o a ssign each syst em interrupt a typ e, depend ing on th e typ e
of device u si ng the in t errupt. When you press the “Press E n ter ” tag, you w ill be directed to
a submenu that will allow you to configure the system interrupts. This is only configurable
when “Resources Controlled By” is set to “Manual”.
IRQ-3 assigned to PCI Device
IRQ-4 assigned to PCI Device
IRQ-5 assigned to PCI Device
IRQ-7 assigned to PCI Device

IRQ-12 assigned to PCI Device
IRQ-14 assigned to PCI Device
IRQ-15 assigned to PCI Device
PCI / VGA Palette Snoop
Choose Disabl ed or Enabled. S ome graphic contr ollers which are not VGA compatible
take the output from a VGA controller and map it to their display as a way to provide boot
information and VGA compatibility.
However, the color in formation comin g from the VGA controll er is draw n from the p alett e
table inside the VGA controll er to generate t he proper colors, and the graphi c controller
needs to know what is in the palette of the VGA controller. To do this, the non-VGA
graphic controller watches for the Write access to the VGA palette and registers the snoop
data. In PCI bas ed sys tems, wh er e the V GA cont roll er is on the P CI bus and a non-VGA
graphic controller is on an ISA bus, the Write Access to the palette will not show up on the
ISA bus if the PCI VGA controller responds to the Write.
In this case, th e PCI VGA contro ller shou ld not respon d to the W rite, it should only snoop
the data and permit the access to be forwarded to the ISA bus. The non-VGA ISA graphic
controller can then snoop th e data on the ISA bus. Unless you have the ab ove situation ,
you should disable this option.
Disabled (default) Disables the function.
Enabled Enables the function.
