Bumping this. It's somewhat about 'maxing out the bandwidth', but also equally about mixing block level iscsi traffic with file level traffic like NFS, CIFS, etc. on the same CPU of the network interface.
Has anyone that has moved to 40GigE to their servers mixed iscsi and file traffic on the...
Conventional wisdom for years and years has been segment your iSCSI traffic onto separate physical interfaces/hardware. Never combine iSCSI and your data traffic onto the same NIC.
This worked well in the 1G days, and this thinking extended as the industry moved to 10G. I remember hot debates...
I've had the opposite experience. I've actually had 6 different tickets that I've opened with Solarwinds in the past 2 weeks and all but 1 has been resolved. The 6th one is a display bug that we're trying to determine where it's coming from since an SNMP walk shows us the correct characters, but...
Although that will probably change soon. My team originally consisted of just the network team, however the Server and Infrastructure teams have been moved under me recently so who knows.
found some interesting devices. anyone used any of these before?

I'm looking for a device that has the following features.
RJ45 plug in to a PoE enabled switch and it will automatically power up.
it will get an IP address via DHCP (and ideally has a little web server built into it but this is optional)
can be monitored with SNMP (required)
thank you. :D
I taught myself. The certs I've gotten along the way are to have something on paper (other than experience) to show for all my knowledge.
As promised, my new stuff:
I'll post some more pics of datacenter1 (pictured above) when I get back into work on Monday. It's a bit messy right now because the techs are using it as a staging area for a few thousand laptops that have come in. It's the only storage area not full right now.
I know some of my engineers just...
It is indeed a public school district. I only operate in the public sector K-12 space.
What you are seeing is an EMC VNX and a Nimble SAN. (2) UCS chassis, multiple UCS C series servers that we're migrating workloads to the blades. Also harder to see are redundant ASR 9K's, redundant Nexus...
I do too. That is why if one of my technicians is giving off 'creepy' vibes to other departments that's something we need to address. Technical problems I can fix with more training (usually). But if you're 33, still live at home and have your mother make you ham sandwiches with the crust cut...
Really what they have is poor 'people' skills. I've interviewed my fair share of engineers and technicians and we typically always try and have at least 1 female as part of the interview committee because often times they get a 'creepy' vibe from some of these guys.
We've ignored those vibes in...
That's why you get a part time job in your expected field (in IT) in college. Going to college full time for a CIS degree while working at a subway or gas station part time for 4 years is a huge disservice to your career.
This article is BS. The real problem is that recent grads come out of school with no experience and turn their nose up at helpdesk or other entry level jobs. They think because they sat in a chair for 4 years and covered some Java scripting, and a few classes on the difference between a switch...
We have both ISE and Prime however I'm not super familiar with either one.
From what I'm hearing in the office neither offer historical reporting and such which is important for the higher ups.
What about SCOM?
At my previous job we had solarwinds. It was nice, but pricey. And honestly we didn't use it to its full potential. We had the SL500 and only monitored about 100 network devices, about 80 servers, and 20 or so volumes.
I'm now at a new organization that is substantially larger and we are...
jesus you people get all bent out of shape about this.
They are NOT queryable. I wasn't even going to waste my time arguing with that idiot but you people don't seem to understand how this stuff works.
The extension attribute that we use to store the last 4 of their SSN is flagged as...
awesome. And let me know how exactly that's going to affect anything?
When you call your cable company they ask for your social, when you call your power company they ask for your social.
Trust me, a lot less qualified people are looking at your social or parts of it in other industries computer...
We store the last 4 of our users SS number in an extension attribute. When we do mass resets like this we typically will combine their last name and the last 4 of their social as their password.
This way we can tell everyone what their password is, without anyone actually knowing each others...
We have sprinkler systems at the schools per local fire code. It is not cost effective to put FM200 systems in the school MDF's because of the relativly low importance any one schools MDF plays in the overall capability of the network.
However the district office is our central MDF for all...
dude, have you even been to the APC website?
They have over 15 different kinds of netshelters
You need to spend some time on that site and figure out what you have, and what accessories are compatible with your specific model.
APC has some...
I know. E-rate is for infrastructure. They don't pay for phones.
However FYI a loophole you can use is that if you buy a qualifying intercom system they will pay for the handsets(phones) used for the intercom system.
They won't be super nice cisco phones, but you might find something cool.
because you mentioned e-rate.
And I guess good luck on this venture OP, but the entire thing sounds very shady. Schools are not businesses. The more you focus on this colo WISP project the less you're focusing on your teachers and your classrooms.
I'm going to stay quiet in this thread but I'll throw this out there OP.
Tread lightly. USAC frowns upon what you're doing and if you submit for e-rate P2 service you have a very high probability that your application will be denied.
I'm also curious what state you are in. Most districts are...
Vlan 5 at site 1 has IP range
Vlan 3 at site 4 has ip range
Your DHCP server at central office is
interface vlan x (at site x)
ip helper-address 10.0.2.50
(assuming cisco switches)
Then on the DHCP server just make a scope for each of those subnets.
