52 PERC H200 and 6Gbps SAS HBA BIOS
The PERC H200 card supports a minimum of two drives and maximum of
10drives for a RAID 0 volume. Two drives are required to configure a RAID 1
volume, and a minimum of four drives and a maximum of 10 drives for a
RAID 10 volume. There can be no more than 14 configured drives in any
system, including a maximum of two global hot spares.A configured drive is a
drive that is part a RAID volume or is a hot spare.
Creating a RAID 0 Virtual Disk
A RAID 0 virtual disk offers the ability to stripe data across multiple physical
disks. RAID 0 volumes offer increased capacity by combining multiple
physical disks into a single virtual disk. RAID 0 volumes also offer increased
performance by striping disk access across multiple physical disks.
Followthese steps to create a RAID 0 virtual disk on a PERC H200 card.
1
Select a controller from the
Adapter List
in the Configuration Utility.
2
Select the
RAID Properties
option.
3
Select
Create
RAID 0
Volume
when you are prompted to create either
aRAID 0 virtual disk, a RAID 1 virtual disk or a RAID 10 virtual disk.
The next screen shows a list of disks that can be added to a virtual disk.
4
Move the cursor to the
RAID Disk
column. To add a disk to the virtual
disk, change
No
to
Yes
by pressing the <+>, <->, or space bar. Asdisks
are added, the
Virtual Disk Size
field changes to reflect the size ofthe new
virtual disk.
CAUTION: All data will be lost upon creation of the virtual disk.
There are several limitations when creating a RAID 0 virtual disk:
• All disks must be either Dell-compliant SAS or SATA HDDs or SSDs.
• SAS and SATA physical disks cannot be used in the same virtual disk.
• HDDs or SSDs cannot be used in the same virtual disk.
• There must be at least 2 physical disks in a virtual disk.
• No more than 10 physical disks are allowed in a virtual disk.
