Configuring Synology iSCSI Storage

In earlier posts we have installed and configured vCenter 5.5 as well as assigning hosts to it, in this next post we are going to configure our iSCSI storage to allow us to later setup Multi-Pathing from our hosts to our storage.

In my home lab I am using a dedicated Synology DS1513+ for my storage, so let’s go set up the iSCSI LUNs on the Synology.

Log in to the Synology interface with your admin account

02-12-2013 22-03-37

In the top corner press the menu button to bring up the above menu, click Storage Manager

02-12-2013 22-04-10

Click on to the iSCSI LUN and click Create

02-12-2013 22-04-30

Click Next

02-12-2013 22-05-23

Choose your Name and Capacity, choose yes for Advanced LUN features (see next box for further details) then click Next

Choose whether or not you’re using CHAP, in my home lab I have decided not to at this time. Click Next

02-12-2013 22-05-58

Click Apply

02-12-2013 22-06-21

Wait for the LUN to be created.

Click on the iSCSI Target tab and then Edit Target-1

02-12-2013 22-08-01

Click advanced and tick the Allow multiple sessions from one or more iSCSI initiators, click OK

02-12-2013 22-08-15

Close the windows and launch the Control Panel

Now we need to configure our network adapters to allow for Multi-Pathing, as the DS1513+ comes with 4 on-board NIC’s I have decided to use 3 of them for dedicated iSCSI traffic from the hosts.




I configured LAN 1, LAN 2 and LAN 3 as my dedicated iSCSI interfaces, they are on the same subnet to allow my use of MPIO from the ESXi hosts, LAN 4 is configured on the same network as the rest of my infrastructure to allow for management of the Synology NAS.

In this post I have configured iSCSI storage on the Synology DS1513+ and set up 3 dedicated LAN connections for our new iSCSI connections on our hosts.

In the next post I will show you how to configure Multi-Pathing on vCenter using the Distributed Virtual Switch
