Moving from physical to virtual servers without careful re-architecting of the environment gives rise to the issues raised in the article and more. The key thing with server virtualisation is that the actual virtual servers should be considered as a resource and rendered anonymous. It's useful to design the environment in a manner similar to clusters, where we talk of "packages" which may be seen to be comparable to "services" in the SOA world view. The next step is to seperate the OS block device from the application and database block devices or filesystems. E.g. it might be optimal to store the application 's program files on NAS and the database on SAN. With EMC Celerra front-ending as NAS we can then define all the constituent volumes as a single device group and then perform TF, SRDF, etc operations on that set without the complications of considering the servers (virtual or otherwise).


I want the ability to copy individual exclusive devices and their specific exclusive computer file systems in addition to support up entire pictures and their specific information.


I like the next phase is to separate the OS prevent system from the program and data source prevent gadgets or file systems.

    I try and write something new 1-2 times per week; less if I'm travelling, more if I'm in the office. Hopefully you'll find the frequency about right!
