Google Enterprise Services

FYI: Do not buy ANY Google Enterprise Services. When you call for support, you get punted to their support forums, and the call handler will drop you after stating there is nothing they can do for you.

I was simply trying to ask how do I go about purchasing MORE seats for Postini, but with that attitude, and case-ownership attitude, I believe I will spend my company's money elsewhere.

Arista Networks Host-Link Aggregation

Setup your server side (I use Broadcom Advanced Control Suite) as you normally would.

On your new shiny Arista 7120T, this is what you need to do:

7120t enable
config t
int et1-4
channel-group 1 mode on

Then run: show int po1
Port-Channel1 is up, line protocol is up
Hardware is Port-Channel, address is xxxx.xxxx.xxxx
MTU is 9212 bytes, BW 40000000 Kbit
Full-Duplex, 40Gb/s
Active Members in this channel: 4
...Ethernet1 , Full-duplex, 10Gb/s
...Ethernet2 , Full-duplex, 10Gb/s
...Ethernet3 , Full-duplex, 10Gb/s
...Ethernet4 , Full-duplex, 10Gb/s

5 minutes input rate 0 bits/sec (0%), 0 packets/sec
5 minutes output rate 0 bits/sec (0%), 0 packets/sec
   0 packets input, 0 bytes
   Received 0 broadcasts, 0 multicast
   0 input errors
   0 packets output, 0 bytes
   Sent 0 broadcasts

Now you're cooking with gas :)

For switch to switch LACP: 

7124-SWB(config)#int et1-4
7124-SWB(config-if-Et1-4)#channel-group 1 mode passive
7148-SWA(config)#int et1-4
7148-SWA(config-if-Et1-4)#channel-group 1 mode active

Once the above sequence is entered and synchronization is complete, the ethernet interfaces 1-4 on each switch are bound to the port-channel.

If you're using another switch with your Arista, the config might be a bit different and you may need to try a few different configs to get it to work correctly.

I just finished the SQLIO testing of the OWC Mercury Extreme Pro RE SSD's.

Platform Details: Dell PowerEdge 6950, 4x Dual-Core AMD Opteron 2.6ghz CPU's, 32GB RAM, Dell Perc 5/i RAID Adapter. RAID details: RAID10, 1MB Stripe Size, Adaptive Read Ahead, Writeback Cache, Windows Server 2008 R2 Standard. I used 4x of the 200GB version of the drive in RAID10 and installed WS2008R2 on that array.

The results were about what I was expecting. See below.

The full details are available here.
