58kW / 31 days (Aug) / 24 hours = 77.95 watts per hour average. I gave the value for the entire month because normal power draw fluctuates quite a bit from moment to moment and when doing other work on the system it was likely to use more power.
Well when you speak in absolute terms is easy to do the math like you just did, but people use the word month loosely I didn't know you mean exactly 744 hours what will be for Aug. Anyways what matters is that your power consumption is really great, especially when you consider the fact that you 6xWD are the one that take 24-30W from those 79W for the whole system , make it really great.
I will look into these. If you have a specific recommendation, I'm all ears.
It seems like they are a lot of choices in the begging of my research, but they are really not that many:
Picking up the brand LSI(Avago) is like picking up Intel for CPU , so It's no brainer.
Then the model - Last model is LSI 936X that is probably not what you want to get, not just it's pricey but , it will take SAS3 SSD's to really take advantage of anything more this card has to offer. On the other end, don't make sense to go older than LSI 926X, because - price and capabilities.
So this leaves in the middle only 2 options LSI 927X (PCIe 3.0, Dual 800 Mhz CPU, 1GB Ram and can use battery or super cap) or LSI 926X (PCIe 2.0, Single 800 Mhz Cpu, 512 RAM and use battery pack)
They are both great options depends how much you want to spend, and I have both of them.
One thing to keep in mind if you don't know the last number where X is like in LSI 926X could be 1 or 0. It's the same card but if it's 1 ports are on the back of the card , while if it's 0 they are on the side. For me this is a dealbreaker cause I use chassis and can only take the model with ports on the back like LSI9261 , but if it don't matter to you , then you'll have more options the get whatever you can find cheaper. And for some reason the options for "0" with ports on the side are much more.
I agree and have been looking but I want to ensure the switch has the capabilities I desire. I have no plans to rewire my entire house with new switches, that would be 4 switches (one 8 port and three 5 port).
I follow
@greco advice and bought Dell Powerconnect 5524, actualy I got 5548 model cause I can't see getting only 24 ports , but it's the same thing otherwise. I've been very happy with it and it has 2x10Gb ports. I don't use it for VLANs, cause I did run more wires around the house in order to have less switches, but if anything changes I can manage it with GUI or CLI.
