Scalent Systems is using infrastructure virtualization to further justify and broaden the use of a SAN. Infrastructure virtualization allows you to create a small group of physical servers that are powered off but connected to the storage and IP networks. The ability to move or start new application instances in a matter of minutes after powering on and booting what was a cold, bare-metal server can be easily done. Infrastructure eliminates the need to create flat open networks that are common workaround to the internetworking issues created by virtualization.”]
