Testing out Neokast to push a 887 kbps live video stream (640×480 24 fps). Seems to be working pretty well, only downsides are that it is Windows only and requires a plugin. We had around 25 users on it earlier today with no major hiccups.

You can check it out during any one of our Holy Pascha services this week.

New HP ServersMost of our infrastructure is running on ancient Dell 6450 servers with quad PIII 550 processors. We have been looking forward to making the jump to a virtualized environment and the pieces necessary to make that happen have just arrived.

Yesterday, we managed the new servers outfitted with the additional hard drives, memory and processors and then load them into the cabinet. We will use the top two servers to run VMware Server on top of CentOS and the bottom will be our “SAN” running iSCSI Enterprise Target on CentOS.

Specifications:
VMware Servers (both boxes are identical)
HP ML370G5
2 Dual-Core Xeon 2.66 Processors
10GB ECC DDR II SDRAM
HP Smart Array P400/512 Controller
2 72GB 10K SAS

SAN
HP ML370G5
2 Dual-Core Xeon 2.66 Processors
4GB ECC DDR II SDRAM
2 HP Smart Array P400/512 Controller
16 72GB 10K SAS
SATA RAID Controller
2 750GB SATA

We had purchased a 3ware SATA RAID controller for use on the SAN box but it looks like there are memory allocation errors at the BIOS level that neither HP or 3ware have done anything to resolve so we are researching another option.

For the next few days we will just work at getting the cabling tweaked and the hardware tested and verifying driver support in CentOS.

Just wrapped up MinistryTECH and CITRT, it was truly an amazing time of fellowship and learning from my fellow Church IT brethren. Today’s quiet time reflects what is on my heart…

we are bound to give thanks to God always for you, brethren beloved by the Lord, because God from the beginning chose you for salvation through sanctification by the Spirit and belief in the truth, to which He called you by our gospel, for the obtaining of the glory of our Lord Jesus Christ. Therefore, brethren, stand fast and hold the traditions which you were taught, whether by word or our epistle. Now may our Lord Jesus Christ Himself, and our God and Father, who has loved us and given us everlasting consolation and good hope by grace, comfort your hearts and establish you in every good word and work. 2 Thessalonians 2:13-17
