What are you running on the server, I'm just curious why you paired 16GB up with an i3?

2008r2 server as the host for hyperv, then 4 vm's inside that, one trix box, one debian server my remote system that i use for email simply accounting files ms word and outlook etc etc, then another one for other stuff.

It's my baby, :) plus it was a learning box to learn how all this stuff work and how to get it working properly etc etc.

Now to figure out how to build and design a backup solution.

I still have a few other things to figure out with this box.

THEN i'm building a storage server for the house for all my stuff :)

I've found this to be the case as well.

Yes me too, i ran all the stuff ^^ above on a dual core 3.0 gig with 4 gigs ram everything ran fine, just needed MORE ram.

However i built this system with better parts * more reliable ones * and raided set's and faster network cards.

New system is DEFIANTLY faster lol!
 
I kind of want a tz210 from work... Mostly so I can break stuff on there instead of production

thats why i have one :) fully licensed and working good, took few days to setup things. but it was my learning toy.
 
Active PFC working on 100V to 240V just means that you need to find a 480V or 600V outlet.

Or hell, be a winner. Get a pole pic off eBay. 13kV should do it.
 
So heres some more updates on the project im working on. The contractors got the walls of our server room up... we had pulled out our lines from the upstairs down to basement and stretched them the length of basement.. but when they did walls they had to pull all wires into the middle of room.. so i'll have to sort through wires still... i have a 10' x 12" cable ladder thats going against the ceiling to organize the cables. then it'll drop into a patch panel (or on the side wall for alarm/access control/cameras)... theres also a server cabinet for the servers.

access panel is in, they MAY paint it, not sure, i think they should paint it so it blends in. they only did their primer so far. but at least i can get access to the 4 holes we made so i can run wires in the future.

next week we start running wires to the building next door (which is there building, we are connecting the two buildings)... which requires outside piping since the one building is taller then the other... and we have to get the relay rack installed/etc...

are you running copper between the two buildings? If so make sure they are both grounded at the same place or PD could cause you a bit of trouble
 
PD? Police Department??? I dont think we're running copper, just a few cat5 cables. The contractors will be knocking a doorway into the next building once they are finished and get inspected, they have to get a C of O on this place once its done before they can knock out an opening and then merge C of O's between the two spaces. Im just running cat5 (3-4 i guess) so i can connect the two networks. If they want TV they can call cablevision and have cablevision run new lines into the new space.
 
Yep ground potential difference is a bitch. I have a friend who works for a school system. The main high school building has the network and internet connections. The school system got "trailers" to augment the lack of classroom space. They're about 75' away from the main building. Originally they had CAT5e running to the trailers. Once a month, a port on the network switch would blow out on the switch in the main building. Turns out the problem was ground potential difference. They replaced the CAT5e run with multimode fiber + two transceivers and all is good now. Ground isolation is a good thing. If the trailers get struck by lightning, the potential for a surge back to the main building is greatly reduced if not eliminated.

Edit: unrelated photo of fiber termination + transceiver. Note I did none of this fiber or wiring work for this client. Was already like this when I started working for him. I've love to clean up the wiring here, but the client is pretty tight with his pennies.

isn't fiber only gigabit fast ? or does it go faster depending on the cards used..?
 
you can get 100Gbps fiber if you have the £$£$$£

you will need a switch on each end with an SFP port and the transceiver modules. We use 1Gbps multi mode as its cheaper
 
You can also use standalone transceivers (as pictured above) if your switch doesn't have SFP ports. I picked up some 100Mbit Transition Networks Just-Network-It transceivers for about $120 a piece if I remember. No frills but has a lifetime warranty. You can wallmount them as well with an optional bracket. You can also power them via USB cable if you are near a computer. I chose to use a regular DC wall wart instead.
 
I used quite a few of the fiber to ethernet adapters at St Joes before they had any money to buy real network gear for between the buildings.

Worked so well they had to get a faster internet connection.

nope, all major backhauls are fiber. They are typically 10 or 40Gbps, although you can currently do over 100. I use FCP for my ESX datastores, as we use 4Gbps fiber HBAs, and 8Gb is common now as well.

Yeah, id like to learn lots about fiber, im hoping to build a storage server, then put a fiber card in it, then have it linked to my fiber port on my new dell switch.
 
If you want to learn about fiber, get some cable and start terminating. Then you'll learn about connectors, types of cabling, loss, bend radius, etc.

heehee, you've got some reading to do.

FCP != IP

with a SAN, you won't be using a dell network switch. You need a fabric switch to do what you are talking about. Fiber is just a medium that information can travel along, just like copper. Just because your PSTN service uses a cat5 cable, doesn't mean you can route analog voice traffic though a network switch.

money for tools is limited :)


BUT i do have a few boxes of these.

I bought some cable and cards and a switch a while back but think i may have made a similar mistake not being 100% sure which bits are FC and which are IP. Sometimes the only way you learn!
 
Took me a while to figure that out but when it comes to storage it's a whole different style of equipment. The fiber switch is NOT an ethernet network switch, and the fiber cards are NOT network cards, they are strictly for storage. The cards are usually refered to as HBAs (host buss adapter). When everything is plugged in the PC basically sees the storage as a local disk.

im going to do fiber ethernet.
 
I'm guessing someone let the electrician terminate everything.

"patch... panel...?"
 
Yikes. Had a good one today. Got to rip out one of my own installs that has been bothering me for over a year.

So I started with this clusterfsck that I am horribly ashamed of:

Had maintainence run 9 new lines for the frikking 9 new PoE IP cameras they needed and then cleaned everything up into this to new cabinet and switch:

Forgive the ghetto boxes, but I had a few original runs that were too short for the new cabinet and had to extend them. I am going to get some fresh double sided tape on Monday so they are just not dangling like that.
