Here’s the setup. We have a core switch of 2 Cisco 3750s, connected together for fault tolerance as a single logical switch; we also have several ESX 3.5 hosts with 4 Gigabit Ethernet NICs installed each. The Virtual Machines will all be on VLAN 8 (reserved for internal servers) and the VMKernel will be on VLAN 107 (reserved for VMKernel traffic like VMotion). I want to create a load balanced, fault tolerant aggregate of these four NICs over the Core Switch.
Having recently installed an ESXi server, I am getting to grips with the management and administration of it, one of the things that I wanted to be able to do was connect to the remote terminal through SSH.
I downloaded my SSH client of choice, PuTTY, and set about connecting, however the server refused the connection. It seems that SSH is not enabled out of the box for ESXi and you need to go through some steps to get there - I found some helpful hints here.
I’ve recently had to upgrade my VM Server due to an increase in load. I had 2 virtual servers running off of the same hard disk, with 768mb of RAM split between the lot. After jamming 2 new 1GB sticks of DDR in, and a new 120GB hard drive it was time to re-allocate some of these resources…here’s how: WARNING! You should always perform a backup on a server you can’t afford to lose BEFORE any operation that could potentially destroy the disk (think what would happen if you had a power cut while resizing…) Step 1 - Moving the Virtual Server.
