This summer's (minor) network upgrade.

So, on Friday we started working on extending the data center. What we've done? Well, in order to accommodate the FPSO we really had to work a lot. Started at 20:00 on Friday and finished next day at 12:00. So about 16 hours. First thing done was cleaning the cabinets (ie throwing all the old cables and laying down new ones). Now what's so cool about this is that it will make life a hell lot easier since... well, i will later post a picture with the old cabinets so you'll get the big idea why now it's easier. Next, since the fiber leads were not in place yet (in the new trunking), we had to find some other leads and put them on top of the cabinets. Not a very elegant solution, but it worked. Next, since we Distribution and Access were collapsed into two Cisco 6509 switches doing HSRP. Since we had to accommodate lot of servers for the FPSO, we decided that the 6509s should be placed in the WAN part. So two stacks of 4x 3750 switches were set in place of this 6509s and .... well, to make a long story short , we switched from L2 to L3. Everything seems more organized right now, some parts have become more redundant (we had HSRP only on 6509 switches, now this moved to WAN part and everything became more redundant since everything has 2 or 3 fibers connecting here. Not to mention the new cabinets which each have 2 ups's , and since each router has two power supplies , each router is connected to two different upses. ) Tunnels are now terminating on a 3800 router (they were terminating into a 1800), and soon we'll change the raw internet router (now a 3620 which is barely over the minimum of what we need. not to say that with NBAR on place it used to choke before enabling NBAR on remote routers as well). Moved everything from Vlan1 to Vlan50 (at least for management purpose), made vlan400 for .187.0/24 class (Connecting the oil rigs ,remote locations and so on). Also Rami was kind enough to do some more overtime (I guess the guy spent about 24 hours here), and also upgraded the Call Manager so now it doesn't take like 15 seconds for each login/logoff.

The major network upgrade is not written (but took place). Kept me for almost 37 hours awake. Will post this at a later time.
