Mainframes<br />
The mainframe computer platform (also known as large computer or<br />
host) that was once given up for dead has been experiencing a second<br />
life. At this point, IBM, with its System-z machines (see image to left), is<br />
practically the only supplier of these monoliths.<br />
The mainframe falls under the category of servers as well.<br />
System i (formerly called AS/400 or eServer, iSeries or System i5) is a<br />
computer series from IBM.<br />
IBM’s System i has a proprietary operating system called i5/OS and its<br />
own database called DB2, upon which a vast number of installations run<br />
commercial applications for managing typical company business<br />
processes, as a server or client/server application. These can typically be<br />
found in medium-sized companies.<br />
The System i also falls under the server category. Some of these systems<br />
can be installed in racks.<br />
Storage Systems<br />
Storage systems are systems for online data processing as well as for data storage, archiving and backup.<br />
Depending upon the requirements for their application and for access time, storage systems can either operate as<br />
primary components, such as mass storage systems in the form of hard disk storage or disk arrays, or as<br />
secondary storage systems such as jukeboxes and tape backup systems.<br />
There are various transmission technologies available for storage networks:<br />
• DAS – Direct Attached Storage<br />
• NAS – Network Attached Storage<br />
• SAN – Storage Area Networks<br />
• FC – Fibre Channel (details in section 3.8.3)<br />
• FCoE – Fibre Channel over Ethernet (details in section 3.8.4)<br />
Some of these storage architectures have already been mentioned in section 1.2 that describes the basic elements<br />
of a data center.<br />
Storage Networks<br />
NAS and SAN are the best-known approaches for storing data in company networks. New SAN technologies like<br />
Fibre Channel over Ethernet have been gaining in popularity, because with FCoE the I/O consolidation from<br />
merging with Ethernet LAN is attractive for infrastructure reasons (see section 3.7.2.). Nevertheless, all storage<br />
solutions have disadvantages as well as advantages, and these need to be considered in order to implement<br />
future-proof storage solutions.<br />
