The scenario: ESX 4.1 Cluster and a Solaris 10u8 64 bit VM running on RDM Luns. Clone the LUNs at the storage level (a crash consistent cloning) and map them to a new VM configured in the same exact way, same virtual hardware version, same SCSI Controller, same Hard Disk SCSI [...]

I finally convinced my friend Toccio to release JABS in the public. JABS, Jast Another Backup Script, is a very handy backup script for VMware ESX and VI3 (I’ve not yet tested on 3i, dunno if it will work). I’ve worked for severals years with VMBK from Max Daneri, but Max is not developing his script [...] At least AMD has released its Quad-Core Opteron CPU and we also have a comparison in term of VMark. It seems that 16 cores AMD Opteron 8360 SE @2.5 Ghz have a better overall score than 16 cores Intel X7350 @3.0 Ghz (both on DELL Platform R900 and R905). The VMark Results are here. ((enjoy)) An interesting post from vmware.com performance blog about the scheduler of VMware ESX and the so called “Simultaneous scheduling”. It’s an ineresting proof of the fact that adding more vCPU to a VM not always take you the expected benefit. As an aside note, in this post there are interesting considerations about the scalability in term of [...] The scenario is the following: - SAN migration from an old EMC Clariion CX-500 to a new CX3-40 - Several Vmware ESX 3.x nodes all with 2 HBAs The goal is to migrate all the VMware LUNs to the new SAN using EMC SAN Copy. All the host will be powered off (yes we can live with this…). The main [...] It seems that from Linux Kernel version 2.6.24 the standard VMware Tools shipped with VMware ESX 3.5 (at least) do not compile. It is necessary to download the Open Virtual Machine Tools and to make the following trick: # tar -xzf open-vm-tools-*/modules/linux |
