My current situation sits as follows. We have zero rack space. Literally none. I can't even rack up our new IBM x3650 M2 servers or the NetApp FAS2020a SAN for the vSphere migration. Thus, I have to make space by virtualizing a few boxes first. I thought about going ahead and unboxing the x3650 systems and setting those on the ground, wiring and firing them up, but then I realized I would have to spend a weekend unplugging all 10 cables out of each server to rack them up, then hoping I made sure to label my cables correctly. So my new plan goes as such: I have a HP DL380G5 w/ 2 Quad Core E5405, 16GB of RAM, 540GB of internal HDD, and only 2 NICs. This server will give me the ability to P2V a few servers to the local storage, then use SVmotion to move those VMs over to the SAN when it's added to vCenter. I already have my switch environment setup with VLANs configured and ready for deployment for my IBM servers. My logic follows as such: |

There was some talk going on the past 2 days about Host NIC configurations. @Kiwi_Si is hosting a poll on his site, TechHead.co.uk,to see the most common configuration among our peers. Which inspired me to create this post. This is what I like to do on my configurations. Use the 2 on-board NICS with 2x4Gb Expansion NICs, giving me a grand total of 10 NICs to play around with. Here is a diagram of how I plan to design my vSphere NIC layout. I still haven't fully configured Fault Tolerance on a set of physical servers, so let me know if you see something is amiss. Thanks to a pointer from @darylhunter, be careful mixing the On-Board Broadcom NICs w/ the Intel 4x1Gb PCI NICs. There can be issues such as flow control. |

Creating a DNS entry for a webserver across an IPSEC Site-to-Site VPN Tunnel |

We are moving a particular server offsite to a remote data center and they are now hosting the server and application. We have established an IPSEC Site-to-Site VPN tunnel using two ASA5510s. We were given an IP address of the server that will now be hosting our application. If I go to http://147.XXX.XXX.84/app then the login form pops up, I enter my credentials, and everything works with no problems. I want to try to make things easier on our users so they don't have to remember the IP address so I tried creating an A Record() DNS entry in our Windows 2003 DNS server. If I create the A record and I try to access http://Arecord/app, the login form pops, I enter my credentials, then I get an error. I believe that error is happening because the address is now http://Arecord.mycompany.org/app/JumbleGarbageTheAppUsesForNavigation. |

EMC as an investment opportunity? |

A friend of mine sent me this MSN Money article last night, A Tech Stock To Own Now. It discusses the rise, fall, and steady growth of EMC stock. He knew I was into virtualization and that I might be of some help. He wanted to know if EMC would be a smart investment for his stock portfolio. At a previous employer, I was a Network/VMware/SAN administrator for an EMC NS40 and NS352, so I have a little bit of experiance playing with EMC products. It's no V-Max, that's for sure, but here was my response. Take in mind, he doesn't know anything related to virtualization or SAN technology and that I know nothing about the stock market or investments. I'm also not an EMC guru, so I don't know the ins and outs of EMC, this is just my own opinion. "EMC is the largest SAN (storage area network) player in the game. Back in the 90s they were one of the ONLY players in the game, and they did it the best. They gained a huge market share and once you go with EMC, it's hard to turn back. The whole IT world is headed towards virtualization. Currently, Data Centers are being virtualized so servers are more robust and have greater efficiency. It is already common that organizations have adopted virtualization, or they are messing with it. Up next is going to be desktop virtualization, which might only be 2-4 years away from hitting mainstream because its almost ready for wide-scale deployment. VMware is software that enables virtualization, while EMC is the storage behind all of that. The fact that EMC owns VMware, lets them see a profit from that, even though you can buy VMware stock.
