i6000 Status

The i6000 is on holding pending the end of FRC Build/Competition season. RoboLoCo is doing well so far this year but mentoring is a massive time sink. Oh well, ton's of VTO for me!

At last check the i6000 doesn't boot with other controllers installed. The next steps will be to monitor the serial output during a normal boot and then compare that with other line card boots. 

i6000 Arrival

The i6000 arrived yesterday. It's unpacked, off the skid, and in the garage. After putting a few bolts back in (holds the two chassis together) and bolting a few other things back on it's powering up and robotics are on. It shows as online.

However the drives aren't showing up. The UI indicates a few issues probably related to the CAN bus. That all seems connected though. So I'm not sure what's up right now.

Scalar i500, i2000, and i6000 Security - Service Account

If you're using a Quantum, Dell, or ADIC Scalar product you should check to see if the password of the GUI's 'service' account is static. If it is then there is a pretty trivial way to get into the system using the vendor's maintenance account. The one system I have access to, an i2000, has a login of service:10101100. 

Scalar i500, i2000, and i6000 Security - Service Port

If you're using a Quantum, Dell, or ADIC Scalar product you need to make sure the 'service port' isn't remotely accessible. If it is then there is a pretty trivial way to get into the system as 'root'. The port is explicitly listed in the manual as not for "normal" use. 

tl;dr If you aren't plugging in stuff you shouldn't (per manual) then the risk isn't that bad. 

Mirrors Are Back Up - Sorta

My yum mirrors are back up and stable. Although they're 100% on my home infra atm. Long term I plan to use an OVH-Virgina set of VMs to act as caching proxies before hitting my home.

Tape Library: Why Tape?

While discussing my new tape library a friend asked "why tape?" 

The answer is pretty simple: 

  • LTO-6 is $7.58/TiB
  • 8TB HDs are $24.83/TiB

At the end if the day I can get tape for 1/3 the price of hard drives. While the upfront cost of tape is higher ($4500 for tape vs $1500 for disk), it becomes worth it pretty quick to me.
