Several months ago I had a very short encounter with a Dell Compellent storage array which had just been installed for a customer in their New Jersey office. In a short blog I showed that creation of a 250GB VHDX could be done in just a few seconds. This was the result of Compellent’s support for Microsoft Offloaded Data Transfer (ODX).
In the current project I have access to an HP 3PAR P10000 V400 with HP 3PAR OS v3.1.2 and just wanted to get some idea of 3PAR’s ODX capability in a customer environment with Windows Server 2012 servers. HP 3PAR StoreServ storage is ODX compatible beginning with the HP 3PAR OS v3.1.2 (December 2012). The servers we are testing with are HP ProLiant DL380 Gen8 (32 logical processors, 256GB RAM) and are configured as Windows Server 2012 Hyper-V servers and some as SMB3 Scale-Out File Servers directly connected with 3PAR for the backend storage. The servers I use for testing are using a 10Gb Ethernet ISCSI connection using redundant Juniper EX3300 switches. The SMB3 File Servers and Hyper-V Fabric Management cluster nodes are connected to redundant 10Gb Ethernet Arista switches, just like the Internet facing Hyper-V tenant cluster nodes. The tests are done on servers with direct 10Gb Ethernet ISCSI connections to the 3PAR storage array.
