Since I work mostly in small offices with "regular" users, I don't see as much Linux or Unix as I used to. Windows Server 2003 is the norm, mostly with Windows XP and Vista clients. I see lots of Cisco routers, random ones provided by ISPs and VoIP vendors here an there. There are some Cisco switches at my clients' offices, but they also use a lot of Netgear, Linksys, Dell, and HP switches. Most of the time we see either Cisco PIX or SonicWall firewalls, but I've come across a couple of Checkpoints as well.

In my past job, where I worked for a datacenter/ISP, there was pretty much nothing but Cisco routers and switches, and we rolled out primarily Windows Server 2003 and Red Hat Linux Enteprise Server 4 (and later, 5) to our customers. We also did some FreeBSD 6.1 and 6.2 deployments, in addition to some support for Solaris 10 for a couple of our government clients. It really varies, what technologies you're going to see, on what type of business environment you're working in.

If I had to pick the top IT stuff we worked with I'd say it goes:

1) Cisco 7940 IP Phone/Call Manager
2) 2950's...most users were coming off 2950's, including their phones (external power used)
3) Orthogon/Red line LOS systems...connected remote sites
4) 2600 series routers..these were mostly at the remote sites, but we were constantly working with them, since the Ortho/Red line shots were run through these.

Edit: That's all the hardware (minus CallManager...), here's the top software we used:

1) Solarwinds SNMPc, to monitor the network
2) Active directory..."I swear, I'm using the right password...."
3) Outlook/MS Exchange 2003

1. Juniper Firewalls SSG's (HA Cluster and AV modules) Netscreens < Used by our SMB customers

2. Cisco Routers/Switches 2960 3750's 2600's< Used by our larger customers.

3. OS - Windows, only some require linux, mainly for webservers.

4. VOIP - Larger customers have call manager of course, smaller have Nortel BCM's (which makes sense considering cost).

In the real world environments I've seen...

- MS Windows Server 2003 NOS
- HP Switches
- Cisco Routers

Most places are decommisioning Novell Servers and going to AD from the look of things. But from what I read Novell is still a better and managable then AD. But I guess it doesn't pay for the extra cost of licenses and implementation of both Windows and Netware, also it's much simpler just to have an AD environment.

Some of the companies I work with use SUN equipment.

Mostly what I see in regards to routers is Cisco. A few companies I work with use Juniper and one uses foundry, but 98% use cisco.

For switches, mainly all the large switches tend to be cisco, 6500's are popular. customers love to stack 3550's too. for the smaller switchs I've seen SMC Network Switchs.

As far as Webservers go, its a toss up between Dell and HP. I do think HP has a slight edge where I work, but again SUn Microsystems does have a strong showing. on the low end Ive seen a lot of supermicro servers too.

I have seen more and more companies using f5 networks load balancers.

As far as OS's go Ive seen a lot of server 2003 and some linux. Ive only seen one customer using Mac OSX.

Ive only seen ethernet.

Im not an expert on all this equipment, its only what Ive seen. I work @ a fairly large Data Center with many high profile Corps.

for transport, many companies use DS3's, T-1, Sonet, as well as Fiber. We have some 802.3 Z and 802.3ae for the backbone

The places I've contracted at and also am currently working at having been using Windows Server 2000/2003 with XP clients using AD of course. Haven't run across any Vista yet. SonicWall, Dell, and Fortinet network equipment. Actually haven't seen any Cisco yet, except for a few mothballed Cisco hubs in storage here.
