I didn't get my point across it seems. Let's see if I can do a better job. You have one box which is running 84 instances of a virtual server and another box which has 40 instances. So you have two boxes which can appear to be 124 realservers? >> Trying to find out why people use virtual servers for >> realservers >> The next question then is why don't you have the big server >> which is currently split into 84 realservers as just one big >> realserver?

I understand that its cheaper, less cooling etc to have a single large box than 84 separate boxes. > if i am understanding you to mean you want me to split it > into 84 complete virtual machines that advertise their own > virtual hardware? too much overhead and wasted resources. so you have 84 virtual machines but they don't appear to be 84 individual machines? > we do have several instances where virtualized hardware is > required. we have one host running esx server for just > that need. but by far the most common needs are easily met > using linux-vserver. > > if i understand you to mean combine the 84 servers into > one server running all the services, that cannot be. some > of those are rented colo space and i will not allow a > customer access to our hosts. OK so not all of your virtual instances are being used for LVS realservers. > i have become a firm believer > in context virtuals. what are "context virtuals" (nothing useful found in google). > far less overhead than virtual hardware (who needs 84 > kernels running all doing basically the same thing?). I thought you had 84 virtual machines. Clearly I don't know what you have. What is the hardware running these 84 machines (number CPUs, number NICs etc)? How many virtual instances are realservers? Why don't you just have a small number of realservers, each one getting a larger share of the resources rather than a large number of realservers, each of which gets a small fraction of the resources?
