Introduction

The SANnet II 200 SCSI array is a robust Ultra160 SCSI storage system and worthy successor to the well-established SANnet 3300 series arrays. Fast performance, high availability and simple manageability are condensed into a flexible, versatile, rugged and cost-effective package.

Each SANnet II 200 SCSI array holds twelve 1-inch high disks in a 2U package and is available with dual redundant RAID controllers, a single RAID controller, or without controllers for use as an expansion unit. An expansion unit can also be used as a stand-alone JBOD storage system or as a host-based RAID array when used with volume management software supporting software RAID.

Designed to fulfill a variety of entry-level and midrange requirements, the SANnet II 200 SCSI array is an excellent storage complement to many IT infrastructures. It can be supported by most of today’s host platforms. And the SANnet II 200 SCSI array creates an application system capable of serving a large number of users. For environments requiring very high levels of storage capacity, a SANnet II 200 SCSI array expands to support up to 36 disks by adding two expansion units.

As a key component in a storage network, the SANnet II 200 SCSI array connects to host servers via industry-standard Ultra160 SCSI host bus adapters, and to local and remote management consoles via standard VT100 serial and Ethernet LAN connections.

Key Features

SANnet II 200 SCSI arrays are compact, ultra-dense, super-rugged storage systems that meet entry-level and midrange requirements by providing affordable, enterprise-class performance and availability features, management functionality and configuration flexibility. Some highlights:

￿￿An extremely space-efficient design provides up to 12 disks and redundant or single RAID controllers in just 2U of rack space.
