No real updates today, had to hit the real world and do some work for a change
Thought I would investigate how much power the Virgin Media SuperHub consumes.
12w! I have the wireless turned off too, not too impressed by this and wondering if a different power adapter may improve this. Not too sure it's worth the effort for saving a watt or two.
Spent a little time investigating into layer 3 switches so I can setup the network properly with VLAN routing etc. Unfortunately these all seem like they consume a fair bit of electricity so leaving them on 24/7 is probably a no go.
My plan is to use the 8 port HP ProCurve as the 24/7 switch connecting the following devices:
- UPS
- PDU
- Node0
- WiFi
- Possibly uplink to a layer 3 switch
My requirements for a layer 3 switch:
- As quiet as possible!
- Low power (802.3az would be nice)
- 10GbE uplinks for connection directly to file server
- Static routing (standard feature of layer 3 I believe)
- 24 ports minimum
- Cheap? :laugh:
- VLAN support (again standard feature)
I figured if I ever needed more than 24 ports I could use one of the HP ProCurve's connected to the layer 3 switch and only connect lower bandwidth devices such as my TV, amp, Xbox etc
So far my research has come up with a few models:
Dell PowerConnect 6224/6248
- Cheap, 2nd hand I have found the 24 port for under £200 and the 48 port for around £400
- Can get a twin port 10GbE SFP+ module for£135
- Awful reviews of endless problems with layer 3 routing
HP 2910AL
- Found on eBay for £600!
- 10GbE module is around £400!
HP A5120-48G
- Found on eBay for under £200
- Guessing it's very noisy as has atleast 4 fans!
- 10GbE module is £700+
Cisco SG500X-24
- Around £970 new
- Has 4x 10GbE SFP+ ports built in
- Cisco gets recommended the most
- Possibly low power - 802.3az
- Have read that the SG500-24 version is fanless, not too sure the 10GbE model is though
Now do I have a spare £1k for a switch? No
Not too sure what to do now haha
