Hi, My circunvention to it, is copy the entire DVD as one .iso file to WinXP, mount the .iso as a virtual driver and enable it to FTP server. This preserve all DVD structures. There are a lot of free programs to create the .iso file and to create the virtual drivers.

How many virtual servers per IFL?

2010-12-06 Thread John Cousins
Here we go again! Without success, we've been trying to get the IT department here to adopt z/Linux since 2003! Our zVM licence has been recently cancelled, and I have just had a request from our Enterprise Architects for some costing for z/Linux as they need to compare server virtualisation

If you are comparing VM and VMware, I would estimate that 1 IFL will support about the same load as 5-10 HP blades running ESX. How many virtual severs will VMware support? Depending on the workload sometimes only 1 sometimes 70 per ESX. How many will VM support? Between a few and a thousand per

In my SHARE user experiences presentation I usually warn people against even answering that question. Stephen has a good approach to an answer. My boss thinks I'm a smart xxx when I turn it around and ask him How many rocks can you carry? Obviously, not all rocks are created equally. I've had

How about savings in power consumption. If configured correctly a virtual server won't cost you anything. Well, hardly anything. Running a dedicated server you must size the server for it's peak load. In VM you run multiple servers and if their peak load doesn't overlap you don't need to size for

I will shot gun some of them... 1. Disaster recover is much easier on the mainframe. In effect, no matter what hardware is replaced with what hardware, it is all the same. With PC type servers, the hardware, hence the software drivers are constantly changing. This may force you to

Question about booting root on a multipathed, LVM'd volume on Debian 390.

2010-12-06 Thread Wiggins, Mark
Back in October I asked a question about multipathing in z/Debian. I've since resolved my problem with getting the multipathing device definitions to hold across an IPL, but now I'm having trouble booting with root mounted on a multipathed, LVM'd volume on z/Debian. It appears to be within the

Hi I was encouraged to try this technique - I can see the file structure but the symbolic links are still unresolved. I copied the iso to a USB thumb drive which found a home at H: - I then mapped an E: drive from the ISO using a free Mount'n'Drive manager from DAEMON tools lite. The iso

Malcolm, Over the weekend I took a look at VMUR.CCP source to insert FD_ZERO(), FD_SET() and select(). I thought adding would be trivial. However, when I took a look at the device driver VMUR.C on the internet, I found that the OPEN calls diag_read_next_file and if there are no data(no
