What is a Systems Architect?

Systems Architects have years of experience in the various parts of the systems they work with. Most probably, they specialize in a specific area area of expertise where they began their careers, but have since expanded their knowledge by learning from their colleagues and from life's lessons. To get to their position, they have proven their ability to analyze and understand the needs and constraints of the business they work in. They are responsible for deciding what technologies will provide the best solutions for a business, how to integrate them with existing systems, and how to retire them when they are obsolete.

There are several flavors of Systems Architects.

I am a huge fan of Sun Microsystems. I love Solaris 10. I love ZFS. I love RBAC. I love zones. I really love T2/T2+ processors. I especially love the T5140 and X4450 servers.

One thing I cannot figure out though, is why Sun lets obviously delirious cocaine addicts package their software. Maybe I'm exaggerating but I think that many will agree that Sun's packages leave much to be desired in general. On top of that, Sun seems to have a constant need to move software around and invent new paths- to boldy go where no sysadmin has gone before????

Cisco ASDM recently started giving me the following error: unconnected sockets not implemented.

After checking around, it seems that this is a known issue with newer Java releases, specifically the current version seems to require JRE 1.6u7.

Downgrading is an option but it is unnecessary.

A friend asked me how he could see the network utilization in Solaris. It seems like a fairly simple request but for some reason this is not a simple command line away.
