1.1.1 Product 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:
Access control via
IQN and IP
CHAP security
Jumbo frames
Header Digest mode

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
