There are some great new storage software solutions coming onto the market and this one caught my attention as it gives the ability to turn your vmware host into an iScsi…
The advantage of sharing your local storage is that your vSphere environment can now use the extra features like VMware High Availability, VMware DRS and VMware VMotion and you don’t have to spend money on buying a separate iSCSI storage solution – or fibre channel storage.
As the report highlights though, the major disadvantage is that this puts enormous “pressure”, from an availability perspective, on the main host system. I know the software is also available with a mirroring option but you can still suffer downtime because the VMs running in memory of the failing host will of course crash.
But are you seriously going to risk losing everything by putting all your efforts and resources onto one host? A great idea but unfortunately with a fundamental flaw.
