The System i offers a variety of console options. All of them have some advantages, and also several drawbacks.

Recommendations

Thin Console

The Thin Console is usually included in a new System order. I’ve written an earlier post about the disadvantages of the Thin Console (here). Even though it isn’t the best, it is usually the way to go. After setup, i’ve never had any issues with those devices, they work without problems behind a KVM switch, the only problem is rack integration, because it doesn’t come in a 19″ form factor. The biggest disadvantage is that it doesn’t support LPARs and remote acccess. Most Small Business aren’t able to afford LPARs, so it isn’t really a problem.

HMC

The Hardware Management Console is the way to go. If it is possible, buy the HMC. It is hugely expensive though, but it comes in 19″ form factor, can easily be integrated, you can install an RSA II adapter for enhanced remote access (remote console access is possible by default). This comes at a price, though. A HMC costs about 6000 CHF - you can buy an “okay” Intel Server for that (strictly, the HMC is an “okay” Intel Server).

Legacy

Operations Console

The Operations Console is the most stupid product IBM ever launched. The killer is the fact that it doesn’t run on Windows Server. So you can’t run it on rackmounted hardware, because these usually don’t support Windows XP. It’s a big mess that IBM made for only one reasons: selling HMCs.

Twinax

Twinax works. No remote access, no complicated device, no rack mount, and all consoles are already End of Sale. But if you still have Twinax equipment, the Twinax console is very sturdy and works well.
