1. Introduction
The SilverSATA V-UR controller is designed to fit in a three 5.25” half-height drive bay for easy
integration in any disk array enclosure or server. The controller host base module depends on
varying models with different configurations. (SilverSATA) controller host supports Ultra320 SCSI
channel and five SATA II channels for disk drives. When properly configured, the SilverSATA V-
UR can provide non-stop service with a high degree of fault tolerance through the use of RAID
technology and advanced array management features. The SilverSATA V-UR controller connects
to the host system through an Ultra320 SCSI interface. The host interface on the host may be
located either on the system board, or on a plug-in host bus adapter (HBA) card.
The SilverSATA V-UR allows easy scalability from JBOD to RAID. It can be configured to RAID
levels 0, 1 (0+1), 3, 5, and 6. The RAID function allows one HDD failure without impact on the
existing data and failed drive data can be reconstructed from the remaining data and parity
drives. RAID configuration and monitoring can be done through the LCD on the front.
1.1 System Architecture
1.1.1 Ultra320 Host Interface
The Ultra320 SCSI controller board’s host interface appears to the host system as an Ultra320
target device. The Ultra320 SCSI can support transfer rates up to 320MB per second.
1.1.2 Serial ATA II Drive Interface
The controller board communicates directly with the array’s 5 Serial ATA II drives via a built-in
SATA interface. The SilverSATA V-UR uses the SilverSATA V-UR SATA II I/O controller chip on
each SATA channel to allow the controller to simultaneously communicate with the host system,
and read or write data on several drives. Up to five disk drives can be connected to each RAID
controller.
1.2 SilverSATA V-UR Controller Board
SilverSATA controller has a SATA II controller which supports SATA II support with up to 5
SATA hard drives.
1.2.1 Cache Memory Subsystem
The SilverSATA controller high-performance architecture comes from Intel 80321 I/O
processor, a 133MHz/64-bit PCI-X memory architecture. The data flows through
133MHz/64-bit PCI-X bus makes its high data throughput. Data can be transferred between
the controller and the drives through a high-speed 133MHz/64-bit path at a burst rate of up
to 1000MB/S. The system’s overall performance can support one Ultra320 SCSI host
channel. The controller default supports 128MB on-board cache.
1.2.2 User Interface
Manual configuration and monitoring can be done through the LCD front control pane. The
firmware also contains an embedded management program that can support the RS-232C
(Serial Console) port out-of-band management. The controller can use any of the interfaces
to simplify the setup and management of their associated disk drives. This out-of-band
method is a convenient platform-independent management utility. Users can through this

port to implement Bootable CD VT-100, VT-100 Terminal and HTTP proxy browser-based
management utility.
1.2.3 Controller Firmware
The system provides RAID levels 0, 1 (0+1), 3, and 5 RAID configurations. It can be
managed either through the LCD control panel or by the system-embedded configuration
utilities. Its high data availability and protection derives from the following capabilities:
Online Capacity Expansion, Online RAID Level Migration, Dynamic Volume Extension,
Array Roaming, Global Online Spare, Automatic Drive Failure Detection, Automatic Failed
Drive Rebuilding, Disk Hot Spare, and Instant Availability/Background Initialization.
The SilverSATA V-UR firmware is stored on the controller flash ROM and is executed by
the RISC CPU. The firmware can also be updated through the RS-232 port without the
need to replace any hardware chips. During the controller ROM flash process, it is possible
for a problem to occur resulting in corruption of the controller firmware. Corrupted firmware
in the controller firmware would make the controller inoperable and bring the system down.
The Redundant Flash provides a unique redundancy feature that helps ensure against
controller availability. This reduces the risk of system failure due to firmware crash. In
addition to the stored programs in ROM, the NVRAM stores information.
1.3 RAID Concept
1.3.1 RAID Set
A Raid Set is a group of disks containing one or more volume sets. It has the following
features in the RAID controller. A volume set must be created either on an existing raid set
or on a group of available individual disks (disks that are not yet a part of any raid set). If
there are pre-existing raid sets with available capacity and enough disks for specified RAID
levels desired, then the volume set will be created in the existing raid set of the user’s
choice. If physical disk of different capacity are grouped together in a raid set, then the
capacity of the smallest disk will become the effective capacity of all the disks in the raid
set.
1.3.2 Volume Set
A Volume Set is seen by the host system as a single logical device. It is organized in a
RAID level with one or more physical disks. RAID level refers to the level of data
performance and protection of a Volume Set. A Volume Set capacity can consume all or a
portion of disk capacity available in a RAID Set. Multiple Volume Sets can exist on a group
of disks in a Raid Set.
In the illustration below, Volume 1 can be assigned a RAID 5 level of operation while
Volume 0 might be assigned a RAID 0+1 level of operation.
1.3.3 Ease of Use Features
1.3.3.1 Instant Availability/Background Initialization
RAID 0 and RAID 1 volume set can be used immediately after the creation. But the RAID
3 and 5 volume sets must be initialized to generate the parity. In the normal initialization,
the initialization proceeds as a background task, the volume set is fully accessible for
system reads and writes. The operating system can instantly access to the newly created
arrays without requiring a reboot and waiting for the initialization completion. Furthermore,
the RAID volume set is also protected against a single disk failure while initializing. In fast
initialization, the initialization process must be completed before the volume set ready for
system access.
