In addition to the IBM Flex System V7000 Storage Node, the IBM Flex System Enterprise 
Chassis offers several possibilities for integration into storage infrastructure, such as Fibre 
Channel, iSCSI, and Converged Enhanced Ethernet

There are several options for attaching external storage systems to Enterprise Chassis, 
including:

��

Storage area networks (SANs) based on Fibre Channel technologies

��

SANs based on iSCSI

��

Converged Networks based on 10 Gb Converged Enhanced Ethernet (CEE)

Fibre Channel-based SANs are the most common and advanced design of external storage 
infrastructure, they provide high levels of performance, availability, redundancy, and 
scalability. However, the cost of implementing FC SANs will be higher in comparison with 
CEE or iSCSI. The major components of almost every FC SAN include server’s HBAs, FC 
switches, FC storage servers, FC tape devices, and optical cables for connecting these 
devices to each other.

iSCSI-based SANs provide all the benefits of centralized shared storage in terms of storage 
consolidation and adequate levels of performance, but use traditional IP-based Ethernet 
networks instead of expensive optical cabling. iSCSI SANs consist of server hardware iSCSI 
adapters or software iSCSI initiators, traditional network components such as switches, 
routers, and so forth, and storage servers with an iSCSI interface, such as IBM System 
Storage DS3500 or IBM N Series.

Converged Networks are capable of carrying both SAN and LAN types of traffic over the 
same physical infrastructure. Such consolidation allows you to decrease costs and increase 
efficiency in building, maintaining, operating, and managing of the networking infrastructure.

iSCSI, FC-based SANs, and Converged Networks can be used for diskless solutions to 
provide greater levels of utilization, availability, and cost effectiveness. 

At the time of writing, the following IBM System Storage products are supported with the 
Enterprise Chassis:

��

interoperability guides. IBM storage products can be referenced in the IBM System Storage 
Interoperability Center (SSIC):

For the purpose of this book, we will limit the information to IBM Storwize V7000, and for more 
information about the other supported IBM System Storage products, refer to IBM PureFlex
