Introduction

 

This manual covers the DVA-08K series of RAID subsystems.

 

With its basic hardware redundancy and the capability of fast I/O transfer, the 2U RAID SATA

 

subsystem is an ideal solution to meet the ever increasing demands for addition of storage

 

capacity. Despite its ease of use, the subsystem does not compromise data protection for

 

convenience. The subsystem’s embedded firmware offers the same protection and mainte-

 

nance functionalities as those designed for an enterprise-level RAID solution. The subsystems

 

provide unprecedented configuration flexibility and allow for the customization of storage

 

subsystems to meet specific demands. It is a rigorous and durable subsystem that can be eas-

 

ily configured and operated.

 

Fully featured RAID redundancy (which provides advanced data protection) ensures that the

 

complete range of RAID levels (RAID 0, 1(0+1), 3, 5, 10, 30 and 50) is supported by the con-

 

troller head. A long list of sophisticated firmware functions (dedicated/global hot-spares, bat-

 

tery protected disk cache, configurable reaction schemes against drive errors, remote and

 

real-time array monitoring, and more) further guarantees the overall availability of valuable

 

data.

 

IT managers using the RAID subsystems will be able to rapidly develop a comprehensive stor-

 

age array. And the modular nature of the subsystem minimizes the maintenance effort to use

 

the RAID appliance.

2.1

Product Overview

 

The subsystem comes with two (2) SCSI-320 host channels interfaced through four (4) VHDCI

 

68-pin SCSI ports. The subsystem comes in a 2U-profile rack-mountable chassis which houses

a RAID controller module featuring complete RAID configuration and data protection function- ality. The subsystem’s operation is protected by redundant, hot-swappable power supplies and cooling fan modules. Designed for a high level availability, all major components are hot- replaceable including its Li-ION battery and the RAID-protected disk drives.

The subsystem supports high-density array capacity by its eight drive bays for SATA-II inter- face disk drives. The subsystem facilitates large I/O transfer, over its dual PCI-X buses archi- tecture, and transmission of block I/Os over flexible caching and a dedicated XOR engine. The subsystem is ideal for direct-attached data storage, backup, and retrieval. It combines the capabilities and block-level performance of RAID storage with the reliable SCSI transfer tech- nologies.

Configured arrays are easily combined with multiple ID/LUNs that appear to the host ports, turning massive capacity into manageable units for data-sharing in a heterogeneous environ- ment.

The RAID 2U-profile, SCSI-to-SATA RAID storage comes in two different models. The only dif- ference between the two models is the number of SATA-II drive bays.

SCSI Host Ports

Connectivity: The subsystem features a 320MB/s bandwidth from each of its SCSI host chan- nels. The dual-stack VHDCI connectors on the rear panel facilitate the connection to multiple host computers and combining the storage capacities of multiple RAID subsystems. Its back- ward compatibility with older SCSI protocols requires minimum investment for upgrading equipment. Storage volumes are associated with SCSI ID/LUNs on the host channels. The subsystem firmware provides flexible configurations of storage volumes which include, logical drives in supported RAID 0, 1 (0+1), 3, and 5 levels, logical volumes that consist of one or more logical drives, and the logical partitions of the previously mentioned configurations. These volumes then appear as SCSI targets over the host links.
