<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-GB">I am planning OpenStack configuration for a server rack with the following spec:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Dell PowerEdge R820: <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">+ 4 processors (Intel Xeon E5-4620), 8 cores/processor<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">+ 512 GB RAM<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">+ 8 HDD, 1 TB/disk<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">+ 2*1Gb, 2*10Gb network cards<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">How would it be reasonable to configure controller and compute nodes in terms of vCPUs and memory?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I am planning to use one controller due to shortage of public IP addresses, and I am wondering how many compute nodes I should use?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">A use case of interest is execution of database instances in OpenStack with a write heavy workload.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I was hinted in the “Ask OpenStack”-service that 32 GB, 2 vCPUs per virtual machine may be a good starting point.
