All the virtual machines<br /> share a common data store and each virtual machine has been assigned a disk space<br /> of 100 GB. The environment is managed by virtual center.<br /> Total number of VM's = 4VMs x 4ESX = 16 VMs.<br /> Total number of disk space consumed = 16 x 100GB = 1600GB or ~ 1.6 TB.<br /> <br /> Is everything fine so far?<br /> <span style="color:#3366ff"><i>How about cutting down on space used to 800 GB or less?</i></span> <br /> <p /> With NetApp built-in deduplication technology on storage you can reduce the space consumed by VMware<br /> virtual machines by 50% or more. NetApp dedupe technology eliminates duplicate data at a block level.<br /> Hence there is no significant performance impact to the production virtual machines while running dedupe.<br /> Also deduplication can be scheduled per volume even at a later time. Imagine your scenario where you have<br /> identical say Windows virtual machines. 16 copies of "C:\Program Files" are almost identical even at a file<br /> level. NetApp dedupe runs at a block level and hence the factor of dedupe is very high.<br /> <p /> <b>VMware before dedupe</b><br /> <p /> <img src="http://communities.vmware.com/servlet/JiveServlet/downloadImage/4963/VMware_b4_dedupe.JPG" alt="http://communities.vmware.com/servlet/JiveServlet/downloadImage/4963/VMware_b4_dedupe.JPG" class="jive-image" /> <br /> <p /> <b>VMware after dedupe on NetApp</b><br /> <p /> <img src="http://communities.vmware.com/servlet/JiveServlet/downloadImage/4964/VMware_af_dedupe.JPG" alt="http://communities.vmware.com/servlet/JiveServlet/downloadImage/4964/VMware_af_dedupe.JPG" class="jive-image" /> <br /> <p /> ESX supports three protocols namely FC, NFS and ISCSI for the datastore. All the three protocols are supported<br /> by any NetApp Unified storage system and dedupe works on all the three protocol data sets. <br /> <p /> True benefits of VMware deduplication on NetApp storage<br /> <p /> 1. Save Storage Space by 50% or more<br /> 2. Save costs and reduce your datacenter footprints<br /> 3. Move closer towards a greener datacenter plan<br /> 4. Reduce network bandwidth with less data blocks to replicate to Disaster Recovery site<br /> 5. Dedupe factor more than 90% for backup/archive data<br /> <p /> <br /> For all these benefits NetApp deduplication is built-in feature and freely available to use on all systems.<br /> <p /> Read more on the NetApp 50% space savings program for VMware at <br /> <p /> <a class="jive-link-external" href="http://www.netapp.com/us/solutions/infrastructure/virtualization/guarantee.html">http://www.netapp.com/us/solutions/infrastructure/virtualization/guarantee.html</a><br /> <a class="jive-link-external" href="http://www.netapp.com/us/solutions/infrastructure/virtualization/vmware.html">http://www.netapp.com/us/solutions/infrastructure/virtualization/vmware.html</a><br /> <p /> Let me know your inputs and comments deduplication netapp esx space_savings go_green efficient best_of_the_week storage 50%_guarantee Mon, 12 Jan 2009 04:37:14 GMT smurthy http://communities.vmware.com/blogs/aseantrends/2009/01/11/deduplication-on-vmware 2009-01-12T04:37:14Z 10 months, 2 weeks ago http://communities.vmware.com/blogs/aseantrends/comment/deduplication-on-vmware http://communities.vmware.com/blogs/aseantrends/feeds/comments?blogPostID=2440
