When I wrote about moving VM on ESXi without VMotion or Storage VMotion , I forgot about one neat VMware feature: thin provisioning. Quoting VMware: “(…) Thin Provisioning, a key component of vStorage, allows over-allocation of storage capacity for increased storage utilization, enhanced application uptime and simplified storage capacity management. (…)”. This means that a virtual machine configured with a 20GB virtual disk and only using 7GB of real data will see a 20GB disk but the file will only consume 7GB on the ESX storage. If the VM uses more storage, the file will grow until it reaches 20GB. Since then, you can save the storage for other VM.Continue reading...
Last time, I had a look at storing stuff on Nexenta using VMware ESXi and iSCSI . This time, I’m gonna try the same thing but Windows Server 2008 as the iSCSI client, aka initiator. Should this matter, the Windows Server is 2008R2 SP1, 64-bit, Standard Edition.Continue reading...
Here’s the deal: create a ZFS volume on the Nexenta server, share it as iSCSI and attach it using the software iSCSI initiator from ESXi 5.Continue reading...
I now have a (quite) powerfull server: Intel Core i5 with 4 cores and 16GB of RAM. I want to virtualize as many things as possible. So I installed the free VMware ESXi 5 on the physical server and started populating it with virtual machines. I have a main virtual machine that has been P2Ved and run on the local storage of the ESXi. Then I have a virtual Nexenta that accesses some raw disks of the physical server to populate the storage.
This is how to install and run a virtual ESXi 5.0.0 inside a physical ESXi 5.0.0 instance.Continue reading...
I already wrote about how to enable and configure SNMP on VMware ESXi 5 . But I was quite short on what you really get from SNMP. Here’s a bit more details.Continue reading...
