VMware recently announced the release of VMware vSphere 5.0 along with a new licensing model that was based upon configured vRAM per virtual machine. Your allocation of vRAM increased on each licensing model; the grander the license model (Enterprise+) the bigger the allowance of vRAM.
This has sparked quite a lot of criticism in the channel for those customers looking to migrate to vSphere 5.0. So following all the noise VMware has increased the allowance on virtual RAM so that most customers will not be adversely affected.
VMware's new licensing model introduced on July 12 was an attempt to shift from pricing based on physical resources to pricing based on virtual resources.
Many customers and partners have complained to VMware that the model would restrict their virtualisation (further exacerbating VM stall) efforts by requiring the purchase of more licenses to achieve the same level of consolidation they were accustomed to.
The new vRAM entitlements are as follows:
- vSphere Enterprise+ will get 96GB of vRAM
- vSphere Enterprise will get 64GB of vRAM
- vSphere Standard and Essentials will both get 32GB of vRAM.
The product will still continue to be licensed per CPU as in pervious editions, however VMware are removing the restrictive model of CPU cores and physical RAM per server and allowing the vRAM to be pooled across all VMware hosts in the farm.
VMware also increased the amount of vRAM that counted to each virtual machine to 96GB, meaning that no single application will require more than one vSphere Enterprise+ license. VMware also implemented an average consumption model on vRAM across a 12 month window so that customers can burst for short periods of time without have to pay for the spikes in usage.
The new licensing model should make customers aware of VM sprawl (the increase of virtual machines due to the simplicity of creating them). Equanet recommends that customers increase the density of their virtual machines on physical hosts and leverage DRS to migrate lower priority workloads when high priority applications need more server resources. By implementing a strict policy on virtual machine lifecycle management Equanet also believe that this will ensure organisations leverage their investments in virtualisation; it is a good time to undertake some housekeeping.
