Juniper Virtual Chassis and Equallogic iSCSi

It’s an unfortunate fact that even though Junipers have a great stacking feature (I think that’s how you classify the virtual chassis) there really is no documentation on how to use it with an EqualLogic SAN. There is one document published here http://en.community.dell.com/techcenter/storage/w/wiki/4250.switch-configuration-guides-for-equallogic-sans Of course this only shows a lag configuration. Ok, I’m not a […]

#DELL #EQUALLOGIC Feature Request to Equallogic, please add READ ONLY to specific iSCSI initiator

Dell Equallogic, this has been asked many times. Is there any hope of getting READ ONLY for a specific iSCSI initiator. This will make your customers happy 🙂

Proper Etiquette For Unmounting a LUN or Detaching a Datastore/Storage Device from multiple ESXi 5.x #EqualLogic #VMWARE

So I was complaining to a group of fellow nerds about how much a pain in the butt it is to ‘properly’ remove a LUN from ESX… you know so that you don’t cause an APD incident (you know, accidentally freeze up all of your virtual machines…) So the proper procedure is painful (less painful though than it used to be […]

Equallogic PortForwarding and Server 2008 R2

Well, previously https://michaelellerbeck.com/2009/11/30/so-you-bought-an-equallogic-san-now-what-part-two/ I would use the venerable rinetd to handle portforwarding on windows. But alas, along comes server 2008 R2 and it doesn’t working anymore (actually I never tested, it might work) But, Server 2008 R2 has built in functionality for port forwarding (nifty!) http://www.rickwargo.com/2011/01/08/port-forwarding-port-mapping-on-windows-server-2008-r2/ So I just gave it a netsh interface portproxy add […]
