Chapter 1 RAID introduction
1.1 Features
UltraStor RS16 FS controller is a high-performance RAID controller.
•Backplane solution
•Fibre Channel (FC x2) – to – SATA II/SAS (xN bays) RAID controller.
Features:
•Front-end 2-ported 4Gb FC ports with load-balancing & failover for high
availability.
•RAID 6, 60 ready.
•Snapshot without relying on host software. (optional)
•SATA II drive backward-compatible.
•One logic volume can be shared by as many as 16 hosts.
•Host access control.
•Configurable N-way mirror for high data protection.
•On-line volume migration with no system down-time.
•HDD S.M.A.R.T. enabled for SATA drives.
•SAS JBOD expansion support.
•Microsoft VSS, VDS support. (optional)
With proper configuration, ULTRASTOR RS16 FS controller can provide non-
stop service with a high degree of fault tolerance by using UltraStor RAID
technology and advanced array management features. The controller features
are slightly different between the backplane solution and cable solution. For more
details, please contact your direct sales or email to “[email protected]”.
UltraStor RS16 FS controller connects to the host system in fibre channel
interface. It can be configured to any RAID level. The controller provides reliable
data protection for servers and RAID 6. The RAID 6 allows two HDD failures
without producing any impact on the existing data. Data can be recovered from
the existing data and parity drives. (Data can be recovered from the rest
disks/drives.)
Snapshot-on-the-box is a fully usable copy of a defined collection of data that
contains an image of the data as it appeared at the point in time, which means a
point-in-time data replication. It provides consistent and instant copies of data
volumes without any system downtime. ULTRASTOR Snapshot-on-the-box can
keep up to 32 snapshots for all data volumes. Rollback feature is provided for
restoring the previous-snapshot data easily while continuously using the volume

UltraStor RS16 FS – Manual v.6.0

for further data access. The data access which includes read/ write is working as
usual without any impact to end users. The "on-the-box" implies that it does not
require any proprietary agents installed at host side. The snapshot is taken at
target side and done by ULTRASTOR controller. It will not consume any host
CPU time thus the server is dedicated to the specific or other application. The
snapshot copies can be taken manually or by schedule every hour or every day,
depends on the modification.
ULTRASTOR controller is the most cost-effective disk array controller with
completely integrated high-performance and data-protection capabilities which
meet or exceed the highest industry standards, and the best data solution for
small/medium business (SMB) users.
1.2 Terminology
The document uses the following terms:
RAID RAID is the abbreviation of “Redundant Array of Independent
Disks”. There are different RAID levels with different degree
of the data protection, data availability, and performance to
host environment.
PD The Physical Disk belongs to the member disk of one specific
RAID group.
RG RAID group. A collection of removable media. One RG
consists of a set of VDs and owns one RAID level attribute.
VD
Virtual disk. Each RG could be divided into several VDs. The
VDs from one RG share the same RAID level, but may have
different volume capacity.
CV
Cache Volume. Controller uses onboard memory as cache.
All RAM (except for the part which is occupied by the
controller) can be used as cache.
Caution
Snapshot / rollback features need 512MB RAM or more.
Please refer to RAM certification list in Appendix A for more
detail.

UltraStor RS16 FS – Manual v.6.0
- 7 -
LUN Logical Unit Number. A logical unit number (LUN) is a unique
identifier which enables it to differentiate among separate
devices (each one is a logical unit).
GUI Graphic User Interface.
RAID width,
RAID copy,
RAID row
(RAID cell in
one row)
RAID width, copy and row are used to describe one RG.
E.g.:
1. One 4-disk RAID 0 volume: RAID width= 4; RAID
copy=1; RAID row=1.
2. One 3-way mirroring volume: RAID width=1; RAID
copy=3; RAID row=1.
3. One RAID 10 volume over 3 4-disk RAID 1 volume:
RAID width=1; RAID copy=4; RAID row=3.
WT Write-Through cache-write policy. A caching technique in
which the completion of a write request is not signaled until
data is safely stored in non-volatile media. Each data is
synchronized in both data cache and accessed physical disks.
WB Write-Back cache-write policy. A caching technique in which
the completion of a write request is signaled as soon as the
data is in cache and actual writing to non-volatile media
occurs at a later time. It speeds up system write performance
but needs to bear the risk where data may be inconsistent
between data cache and the physical disks in one short time
interval.
RO Set the volume to be Read-Only.
DS Dedicated Spare disks. The spare disks are only used by one
specific RG. Others could not use these dedicated spare disks
for any rebuilding purpose.
GS
Global Spare disks. GS is shared for rebuilding purpose. If
some RGs need to use the global spare disks for rebuilding,
they could get the spare disks out from the common spare
disks pool for such requirement.
DC Dedicated Cache.
GC Global Cache.

least four hard drives.
RAID 10 Striping over the member RAID 1 volumes. RAID 10 needs at
least four hard drives.
RAID 30 Striping over the member RAID 3 volumes. RAID 30 needs at
least six hard drives.
RAID 50 Striping over the member RAID 5 volumes. RAID 50 needs at
least six hard drives.
RAID 60 Striping over the member RAID 6 volumes. RAID 60 needs at

1.4 Volume relationship diagram
Figure 1.4.1
This is the volume structure of ULTRASTOR designed. It describes the
relationship of RAID components. One RG (RAID group) consists of a set of VDs
(Virtual disk) and owns one RAID level attribute. Each RG can be divided into
several VDs. The VDs in one RG share the same RAID level, but may have
different volume capacity. Each VD will be associated with one specific CV
(Cache Volume) to execute the data transaction. Each CV can have different
cache memory size by user’s modification/setting. LUN (Logical Unit Number) is
a unique identifier, in which users can access through SCSI commands.

3.3 Quick install
It is easy to use “Quick install” to create a volume. It uses whole physical disks
to create a RG; the system will calculate maximum spaces on RAID levels
0/1/3/5/6/0+1. “Quick install” will occupy all residual RG space for one VD, and
it has no space for snapshot and spare. If snapshot is needed, please create
volumes by manual, and refer to section 4.4 for more detail. If some physical
disks are used in other RGs, “Quick install” can not be run because the
operation is valid only when all physical disks in this system are free.
Step 1: Click “Quick install”, then choose the RAID level. After choosing the
RAID level, then click “ ”. It will link to another page.
Figure 3.3.1

Step 2: Confirm page. Click “” if all setups are correct. Then
a VD will be created.
Done. You can start to use the system now.
