  • 1.  How best to size VMs for ESXI host

    Posted May 14, 2018 01:34 PM

    Using 2 Lenovo Hosts with the following processor spec

    Intel® Xeon® Processor E5-2690 v4 (35M Cache, 2.60 GHz) Product Specifications

    It is a Lenovo x3650 M5

    CPU capacity is 72.77GHz

    Memory Capacity is 385GB

    Storage is 50TB

    Is there  a best way to plan how many VMs will be on each host, there are 56 SQL machines

    I see there is a cluster calculator, these two hosts will be on same cluster

    vSphere Cluster Sizing Calculator | CloudXC

    Just unsure on how best to plan this? Any help gratefully appreciated

    Do you have vROps? If not, this would be a great place to start as it has these calculations built-in in a "what will fit" scenario. The fact is, unless you know how these workloads behave and consume resources, it's really just a guess.

    Thanks we dont have vROPs deployed yet

    All things being equal, the machines have 154 CPUs, 151 sockets and 57 cores p\s with 430GB used

    To start with all machines having a similar workload is it straightforward as doing this through RV tools in the meantime?
