Install Wappalyzer Free to cheap(ish) shared storage Hi Guys, Sorry it's taken me a whole to post, enjoyed the user group, just wish there had been more time to chat to people at the break/end - maybe next time! My email address is in my profile I'm always happy to offer advice and share experiences if anyone wants to contact me. In the mean time here's a quick bit on some free, cheap, and not-so-cheap-but-still-not-expensive SAN options. Free: iSCSI Enterprise Target. Make sure you use version 0.4.15 or newer, it has VMware specific fixes relating to reserve/release, if you use an earlier version you will need to apply a 3rd party patch to your ESX host. You can find a guide on setting up IET here, it talks about doing it in a workstation 6 VM, but the proceedure is pretty much identical for a physical server. Cheap(ish): I use SANmelody as the storage for a production machine and have been very happy with it so far. Cheers,

Things that are very obvious to me seem to be not so obvious at all for some other people. So I’ll try to explain these things from my point of view. First let’s have a look at the virtual machine settings available to us. Allocated memory: This is the amount of memory we assign to the vm and is also the amount of memory the guest OS will see as its physical memory. Instead of configuring these settings on a vm basis, it is also possible to configure these settings on a resource pool. This concludes the memory settings we can configure on a vm.

projects Performance Troubleshooting VMware vSphere – Memory | virtual in Introduction As memory prices continue to drop and the x64 bit architecture is embraced and adopted more in the industry, we continue to see a rise in memory demands. Only a few years ago, 1-2 GB virtual machines were the norm, 95% of these being 32 bit operating systems. With processors now more powerful than ever, the general shift of virtual machine limitations is changing from compute to memory. Memory Technologies in VMware vSphere There are some major benefits of virtualization when it comes to memory. Transparent Page Sharing – The VMkernel will compare physical memory pages to find duplicates, then free up this redundant space and replaces it with a pointer. What to look for Check ESX host swapping. Total_active_memory > (Memory_Capacity – Memory_Overhead) + Total_balloonable_memory + Page_sharing_savings Check for Virtual machine swapping.
