Dell R815, 2U as vHost Server Review

I love using the Dell R815 as my vHosts for several reasons:

1. The airflow through the thing is phenomenal. redundant fans, the power supply package, the way the ram is stacked. it’s just laid out really well and really serviceable.

2. I get them with no spinning media. yep, just dual SD cards, and you’re good to go!

3. Dual Power supplies are a given!

4. Slots for extra network connectivity!

5. You can order them with a “half ram / half processor” configuration for expansion later!

6. The AMD processor, in my opinion is the best power wise processor on the market today.

SSH Slow to Login

Ever tried logging into a machine with ssh and found you have to wait much longer than reasonable for the session to start? This happened to me a few times and was especially annoying with machines on my local network (or a VM attached to a virtual network) that should be letting me in immediately. Basically the session is slow to start because the SSH server is trying to lookup the hostname of the SSH client and for whatever reason it’s timing out (e.g., it can’t reach a nameserver, because you happen to be offline) There are a couple of very simple ways to fix that: add “UseDNS no” to /etc/ssh/sshd_config add the client’s net address to the server’s /etc/hosts

Issue Copying a Large Amount of Data to a WD My Book Live Duo

We had this issue copying large amounts of data to this Western Digital My Book Live Duo NAS.

It was mounted up on a Oracle Centos 6.5 VM but once we hit a file over 1GB in size, the machine would halt. Turns out we have to map the drive using the option protocol=udp like the following statement:

mount 192.168.1.45:/nfs /transport -o soft,timeo=60,intr,proto=udp

 

See, NFS mount by default uses TCP, but for Linux to work with this drive it needs to use UDP.

How to Update Force10 S50n Firmware

Here is the Firmware FTOS-SB-8.4.2.7.bin

You’ll need a tftp program installed on your desktop.

Copy the new firmware to your tftp server folder.

Here is the command to upgrade the system

upgrade system tftp://192.168.1.xxx/FTOS-SB-8.4.2.7.bin

Output will look like this:

Force10#upgrade system tftp://192.168.1.xxx/FTOS-SB-8.4.2.7.bin
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Force10#

You can use the serial cable or ssh into the switch to do this operation.

Don’t forget to write, before issuing the reload command.

Here’s an example of my running config:

Pre-Provision Force10 Stack

On your current stack, ssh in and at the config prompt, enter:

stack unit 2 provision S50V

stack-unit 3 provision S50V

the number is the number of the switch you’re introducing, and the S50V is the model of the switch, you can use S25N, S25P, S25V, S50N, and S50V.

On your new switch make sure you renumber the thing at the enable prompt like this:

stack-unit 0 renumber 2

stack-unit 1 renumber 3

 

Make sure you write out your config file!
