Драфт нового Redbook "PowerVM Migration from Physical to Virtual Storage"
Читаем, и пытаемся понять куда катится мир 🙂
IT environments in organizations today are facing more challenges than ever
before. Server rooms are crowded, infrastructure costs are climbing and
right-sizing systems is often problematic. In order to contain costs there is a push
to use resources more wisely – minimize waste and maximize the return on
investment. Virtualization technology was developed to answer these objectives.
More and more organizations will deploy (or are in the process of deploying)
some form of virtualization, however, parts of an organization’s systems may use
legacy storage equipment. How do you migrate from physical, often
direct-attached storage, to a virtual storage environment.
This IBM Redbooks publication introduces techniques to use for the migration of
storage from physical to virtual environments and introduces several new
features in POWER6 technology-based systems. These features include:
The chkdev command, added in Virtual I/O Server 2.1.2 FP22 to assist in
identifying physical to virtual candidates and to ensure device identification is
Extensive use of NPIV technology for both disk and tape
The use of file backed optical technology to present virtual CD media as
