If you ever wanted to know what powers the broadcasts, read on. I unfortunately did not have time to go into too much detail, but you can always open a support ticket if you would like to find out more information.
On first read, you may think that the hardware is overkill but there is more going on in the background than just the NSW GRN Stream.
This is what I host:
- NSW/ACT Government Radio Network [Public]
- South West Sydney Analog Police Network [Private/Under Development]
- ADS-B ground station processor [Private]
- NSW/ACT Government Radio Network Unrestricted [Private]
- Historical Audio Library of Analog Police/Analog GRN/Digital GRN - 10,000 Hours so far [Private/Under Development]
All of this combined requires quite a bit of grunt. Anything that is private will probably remain so simply because I do not have the
money to sustain the bandwidth or to buy more external hosting. Everything under development will be released sooner or later - when I have the money and time
to finish the services.
But lets first dive right into the hardware specifications:
- 2 x Intel Xeon CPUs running at 2.5GHz each with 4 x Physical and Logical Cores each
- 16gb RAM at 333MHz each - Type DDR2 FB-DIMM - those are EEC modules made for servers.
- GPU is powered by a NVIDIA Quadro FX 3700 with 512Mb RAM on-board
- 4 x 256Gb SSD SATA 6Gb/s storage drives plus 1 x 512Gb SSD SATA 6gb/s Server OS Drive plus slow access storage 1 x 1Tb HDD
- 25 Sensors that monitor the temperatures throughout the casing
- 4 x Gigabit Ethernet Ports (2 x 2 NIC Teaming which run directly to the CISCO switch)
- 1 x Atheros AR9285 Wireless Network Adapter only used for emergency up-link to 4g modem in case of router loss
- 2 x 600Watt Hot swap power supplies
- iLO access for remote restarts, shutdown and power on
- Shadow BIOS in case of failure or virus corruption BIOS can be switched easily
- 1 X Intel 631x/6321 ESB2 - High Definition Audio [A-1]
- 2 x Prolific USB-to-Serial Comm Port adaptor to connect Digital Scanners
- 3 x LCD Monitor 24"
- APC UPS to power equipment for 25 minutes after power loss. Also protects against spikes and brownouts. Not against lightning though!
- Several Analog and digital scanners from Uniden with 1 x roof mounted antenna for each
- 2 x Raspberry Pi boards for various tasks such as encoding sound and hosting files
- 2 x Switches (HP/Cisco)
- 1 x Cisco Router/Modem with 4g fallback
- 1 x WSUS and PXE Deployment Server
- 2 Separate networks that operate link a VLAN Network
All of this is kept inside a standard server rack to keep dust out.
- Windows Server 2012 R2
- VMWare - Windows 10 ENT, Windows 7 ENT, Windows 8.1 ENT
- ProScan - Broadcast/Scanner Database Management Software
- QoS Management Software
- Load Balancing Software
- BUTT - Mirror of Main Broadcast and instance two for private broadcast*
- Kasperski Internet Security
- Visual Studio 2016 for Scanner Australia software development
*You probably ask why there is a separate private broadcast. The answer is pretty simple, there are many channels which cannot be broadcast via the internet - either due to sensitive nature or due to request of suppression.
Those channels are L/O (locked out) on the public broadcast but open on the private broadcast. Sorry I cannot give access to this - its basically for myself and friends/family if they are interested.
