<div dir="ltr">This is purely a guess, but I think the fact that we don't use a lot of the features available in ESXI is why Cisco doesn't have us reserve 8gb. I've never had an issue with running out of ram on a production system, always cores.</div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Oct 30, 2015 at 8:58 PM, Anthony Holloway <span dir="ltr"><<a href="mailto:avholloway+cisco-voip@gmail.com" target="_blank">avholloway+cisco-voip@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><span style="font-size:12.8px">Hey All,</span><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">I'm trying to understand the concept of ESXi's RAM requirements, and with 5.5 VMWare says the minimum is 4GB, but they do recommend 8GB for "full features."</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">When I look at this one guide as an example:</div><div style="font-size:12.8px"><a href="http://docwiki.cisco.com/wiki/UC_Virtualization_Supported_Hardware#BE6000H.C2.A0Servers_and_Small_Plus_UConUCS_Tested.C2.A0Reference_Configurations" target="_blank">http://docwiki.cisco.com/wiki/UC_Virtualization_Supported_Hardware#BE6000H.C2.A0Servers_and_Small_Plus_UConUCS_Tested.C2.A0Reference_Configurations</a><br></div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">It shows that 48GB of RAM is installed inside, but only 44GB is available to VMs. That makes me think Cisco is only accounting for a 4GB minimum, and not the 8GB recommended.</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">Is that what you read that as, as well?
