1.1.1Product Introduction

This chapter briefly introduces the SecurStor 16I iSCSI-to-SATA-II storage subsystem. The SecurStor 16i subsystem comes with four (4) GbE host ports capable of large I/O transfers over iSCSI packets.

EMD Storage’s iSCSI storage supports network initiators compatible with the IETF iSCSI standard (RFC 3720) with the following functionalities:

Internet SCSI (iSCSI) protocols are embedded in firmware and I/Os are rapidly processed via dedicated algorithms. The iSCSI storage is built around reliable hardware and sophisticated RAID technologies. I/O requests are packaged and transmitted over local area networks (LANs), wide area networks (WANs), or the Internet using the existing networking hardware and thus the total cost of ownership is reduced. With the help of the networking flexibility, the subsystem is ideal for location-independent data storage, backup, and retrieval.

The subsystem delivers extreme performance that result from the combined performance of multiple disk drives and the level of data protection unseen in other iSCSI storages. Featuring all standard RAID functionalities as other SecurStor subsystems, the SS 16i subsystem provides a reliable platform for IT operations such as backup, data-mining, or strategic allocation.

This subsystem features a high-density architecture that supports up to sixteen (16) hot swappable, SATA-II hard drives in a 3U-profile chassis. The subsystem is powered by a RAID controller board featuring the latest ASIC400, RAID6 ASIC as the XOR engine. The pre-installed 512MB DDR RAM DIMM module can be upgraded to a 2GB capacity DIMM to support complicated applications that hold numerous ID/LUN combinations.

The controller board is housed in a metal canister and is referred to as the “controller module.” The controller module is comprised of a main circuit board, an interface faceplate, and a metal canister. The controller module is accessed through the rear of the SecurStor 16i with the help of ejection levers. An optional battery backup unit
