The Kingston solution resulted in a number of benefits for VMware's environment.
Able to take on more workloads with confidence
The Kingston memory upgrade doubled the capacity of the VMware workloads running on top of them.This result is consistent with an independent study of Kingston memory that found that the number of virtual machines a server could support increased proportionally with the increase in RAM.
In addition to doubling workload capacity, the Kingston memory increased the average number of instances that could run on each host by 150 percent, (from two instances on a 48 GB host tofive on a 96 GB host). Moreover, the IE Team averages 11 virtual machines per instance with some that can support as many as 27.
With memory headroom to spare, the IE Team can accept more application workloads from internal customers. For example, in 2011 the Team completed six onsite beta tests. In the first half of 2012 it has completed eight tests and is on track to complete up to 25 by the end of the year.
And while the 2011 VMworld Hands-On Lab events tallied 31 labs with 144,083 virtual machines deployed, the added server memory can handle even greater workloads for future events.
Competitive pricing enables operational efficiencies
The Kingston memory offered a competitive list price significantly better than the OEM's discounted price. Consequently, 288 servers were upgraded to 96 GB of memory to bring the entire installed base of 416 serves to a uniform memory footprint.
Operationally, the uniform 96 GB servers make it easier to implement automated provisioning. And through that automation, the Team expects to manage workload distribution even more efficiently.
VMware's CAPEX budget also received a boost. The service life of installed servers was extended by supplementing them with more memory versus the capital-intensive alternative of procuring newer ones.
Reliable modules support high-availability objectives
The reliability of the Kingston modules is an added plus in production environments. The company incorporates rigid quality assurance measures into its manufacturing operations and vigorously tests modules to ensure that they meet its high standards. That's consistent with Zimman's personal experience. In over nine years of using Kingston memory, he can't recall experiencing a single DIMM failure.
