I'm a total outsider to SunStorage, even though I work for Sun. Information here shouldn't be taken as official, but rather, a perspective from just one user.

I was playing with SunStorage Simulator over the weekend. AFAIK, this is just a VMWare image of the same software that runs in real Sun Storage 7000.

Initially I found it bit odd that they provide VMWare image and not VirtualBox image (which is another Sun product), but later I realized that this is because of the lack of SCSI emulation in VirtualBox — the VMWare appliance comes with some 16 SCSI disk images to emulate the storage.

The next thing I noticed is that this appliance doesn't give you a shell access. It does run ssh, so you can remotely login, but instead of a real shell, you get aksh, which looks and feels like zoneadm (except with a different command set.)

This makes sense as an appliance, but what I wanted was to rip this apart and see how it works, so I wanted a a real shell. The developers of SunStorage seem to be suggesting that there is indeed a shell acess, so I looked around, and after a while I eventually discovered that there's the "shell" command in this aksh to give you bash.

A few other discoveries to note:

• There's no Java in this appliance. Ouch.
• The browser-based UI is built on top ofa custom framework, including the widgets (see them in "https://IP-OF-THE-APPLIANCE:215/demo/"), AJAX RPCs, and judging by URLs of things, controllers too. Ouch.
• Judging from "ls /usr/lib/ak/htdocs/appliance", whoever did this seriously like raw fish in the Japanese style :-) For those of you who don't understand Japanese, I added links to Wikipedia for what they mean (and yes! they are all edible!)
