The best process for disk sizing now is base it on data, not the traditional approach of how many disks do you need.&#160; Allow some budget for purchasing more disk.&#160; You can quickly expand a LUN, then the CSV and then the VHD\/file system.&#160; Next comes the memory.&#160; Basically each GB of VM ram costs a few MB in overhead charges.&#160; You need to also allow 2GB for the host or parent partition.&#160; What that means is that a host with 32GB of RAM realistically has about 29GB available for VM\u2019s. The HP tool is pretty cool because it will pull in information from Microsoft\u2019s MAP.&#160; The free <a href=\"http:\/\/technet.microsoft.com\/en-us\/solutionaccelerators\/dd537570.aspx\" target=\"_blank\">Microsoft Assessment and Planning Toolkit for Hyper-V<\/a> will scan your servers and identify potential virtualisation candidates.&#160; This gives you a very structured approach to planning.<\/p>\n<p>The document talks about the blade components and blade servers.&#160; There\u2019s 3 types of blade from HP.<\/p>\n<ul>\n<li>Full height: These are expensive but powerful.&#160; You can get 8 of them in an enclosure.&#160; Their size means you can get more into them.<\/li>\n<li>Half height: You can get 16 of these into an enclosure, the same kind used by the full heights.&#160; 16 is coincidentally the maximum number of nodes you can put in a Windows cluster.&#160; These are the ones we use at work.&#160; Using Mezzanine cards you can add enough HBA\u2019s and NIC\u2019s to build a best practice W2008 R2 Hyper-V cluster.<\/li>\n<li>Quarter height or Shorties: These machines are smaller and thus can have less components.&#160; Using some of the clever 10Gig Ethernet stuff you can oversubscribe their NIC\u2019s to create virtual NIC\u2019s for iSCSI and Virtual Switches.&#160; I\u2019d say these are OK for limited requirements deployments.&#160; Their custom enclosure can be a nice all-in-one featuring storage and tape drives (note you can also do this with the other blades but you\u2019ll never get the capacities to match the server numbers).<\/li>\n<\/ul>\n<p>What is really cool is that HP then gives you reference architectures:<\/p>\n<ul>\n<li>Small: A single C3000 enclosure with internalised storage.&#160; MSA or JBOD (un-clustered hosts) storage is something I would also consider<\/li>\n<li>Medium: A single C7000 enclosure with LeftHand storage.&#160; I\u2019d also consider MSA or EVA storage here.&#160; LeftHand is incredibly flexible and scalable but it is expensive.<\/li>\n<li>Large: I\u2019m drooling while looking at this.&#160; Multiple (you can get 4 in a 42U rack, with 64 half height blades) C7000 enclosures and 2 racks of EVA 8400 storage.&#160; Oooh Mama!<\/li>\n<\/ul>\n<p>There\u2019s even a bill of materials for all this!&#160; It\u2019s a great <em>starting point<\/em>.&#160; Every environment is going to be different so make sure you don\u2019t just order from the menu.<\/p>\n<p>It\u2019s not too long of a document.&#160; The only thing really missing is a setup guide.&#160; But hey, that\u2019s all the more reason to read my blog \ud83d\ude09<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I\u2019ve not been keeping up with my reading as of late.&#160; I missed that this document from HP came out \u2013 I was distracted with actually deploying a Windows Server 2008 R2 Hyper-V cluster on HP ProLiant Blade Servers and HP EVA SAN storage instead of reading about it \ud83d\ude42 This document appears to be &hellip; <a href=\"https:\/\/aidanfinn.com\/?p=10008\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;Planning W2008 R2 Hyper-V on HP ProLiant Blade Servers&#8221;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_uf_show_specific_survey":0,"_uf_disable_surveys":false,"footnotes":""},"categories":[20],"tags":[64,181,89],"class_list":["post-10008","post","type-post","status-publish","format-standard","hentry","category-hyper-v","tag-hp","tag-hyper-v","tag-proliant"],"aioseo_notices":[],"jetpack_featured_media_url":"","amp_enabled":true,"_links":{"self":[{"href":"https:\/\/aidanfinn.com\/index.php?rest_route=\/wp\/v2\/posts\/10008","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aidanfinn.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aidanfinn.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aidanfinn.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/aidanfinn.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=10008"}],"version-history":[{"count":0,"href":"https:\/\/aidanfinn.com\/index.php?rest_route=\/wp\/v2\/posts\/10008\/revisions"}],"wp:attachment":[{"href":"https:\/\/aidanfinn.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=10008"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aidanfinn.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=10008"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aidanfinn.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=10008"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
