Introduction to iSCSI SAN
The Internet Small Computer System Interface, or iSCSI, is a widely adopted IP based
protocol that provides all the benefits of block-based storage with SCSI compatibility.
Combined with the distance, bandwidth, standardization and low cost of Ethernet, it
also comes with a huge base of IT expertise from those already familiar with Ethernet
and IP. The iSCSI protocol maps SCSI commands over a TCP/IP network and utilizes
relatively inexpensive Gigabit Ethernet (GigE) network components to send blocks of
data over an IP network. As a result, iSCSI provides IT staffs an alternative to existing
solutions, such as Fibre Channel SANs, while combining the familiarity, bandwidth and
low cost of Ethernet with the efficient, speedy, block-based data transfer performance
of a SAN. IP for networked storage is inevitable. In fact, research firm International Data
Corporation (IDC) predicts that iSCSI SAN switch ports will account for 17 percent of the
total port shipments by 2005 as more and more organizations move away from expensive
and complex Fibre Channel components. By implementing iSCSI, organizations have the
opportunity to leverage existing network infrastructure investments while reaping the
benefits of future proliferation of IP based network storage. |

| Introducing StorageConnections.Net QuodCelior iStor
StorageConnections.Net is a storage provider leading the iSCSI SAN revolution.
StorageConnections.Net offers an intelligent iSCSI SAN platform that radically reduces
the complexity and cost of enterprise level, networked storage solutions. Leveraging the
cost and performance advantages of Ethernet, StorageConnections.Net’s architecture
revolutionizes storage by enabling a new generation of open, high performance, easily
scalable networked storage solutions. The StorageConnections.Net QuodCelior iStor iSCSI
Storage Sub-System is a low-cost, flexible, reliable, block-level network storage solution
that assimilates the fabric of Ethernet networks directly into the storage system
platform, enabling unprecedented scalability, availability and manageability.
StorageConnections.Net’s QuodCelior iStor Storage Sub-System is the disk array, or iSCSI
target, in the iSCSI SAN. Organizations utilizing StorageConnections.Net’s iSCSI, networkbased technology will migrate from Fibre Channel components to inexpensive, off-theshelf, industry standard GigE network components. StorageConnections.Net is vendorneutral and operates simply in any open, standards based network environment.
Consequently, the interfaces between the host and the QuodCelior iStor Storage Sub-
System can be from any standards-based vendor, since StorageConnections.Net can
interoperate with a variety of GigE host Initiators and network-switches. In addition,
since the QuodCelior iStor Storage Sub-System is an iSCSI, networked-based disk array, it
is readily available across large networks and can be dynamically scaled in capacity and
performance. Organizations can set up storage volumes/disks from 128Mbytes to as
many terabytes of space that are available. There are no restrictions on the size of the
volumes/disks. Moreover, any number of individual available hosts can initiate these
volumes. IT administrators can easily assign volumes to a single host, they can be redeployed, or they can be shared in a clustered environment. |

| >Combining the strengths of networking
and SCSI to build an affordable and
reliable Storage Area Network (IP-SAN).
The QuodCelior iStor maps SCSI commands over
a TCP/IP network and utilizes relatively
inexpensive Gigabit Ethernet (GigE) network
components to send blocks of data over an IP
network. Supported by software and hardware
heavyweights such as Microsoft, IBM, Cisco, and
Intel, the QuodCelior iStor is poised to bring
SAN technology to the next generation of
simplicity, affordability and manageability.
