Hey all,

Building out my lab, I was going to get a rackmount UPS. The one I'm looking at is a Cyberpower OR1500LCDRM1U. It says it offers:

1500 VA, 900 W, 120 V

Do I understand correctly that all I need to do is find the Wattage rating for each of the components I want to plug in and add them up? My components right now are pretty light, only about 120 watts total. But soon I'm going to expand and build out a Nutanix CE cluster with 3 nodes and a rack of drives. I was looking at using some NUCs but they are each rated at 330W.

So that would mean even the NUCs by themselves would over-provision the UPS right? Then on top of that I would still need all the other equipment in the rack to be powered.

Am I understanding this correctly or is there something I'm missing?

Hey everyone,

I'm back with another question. I'm looking at switches and have it narrowed down to two options:

Cisco Catalyst 1200-24T-4X

Cisco Business CBS220-24T-4X

I'm going to have a Netgate as my main router in the house but I am also going to have a dev environment that I don't necessarily want interacting with my regular network. Originally I was thinking of just getting an unmanaged switch but I might like having some light VLAN capabilities of a managed switch that I can have the option of using.

I don't have any use right now for PoE devices so I don't need the switch to do that. I'm having a hard time figuring out exactly what the differences are between the CBS model and the Catalyst model.

It's a difference of about $45. As far as I can tell, the main benefit to the Catalyst is Cisco's Cloud dashboard. I don't need or want that. I'll handle everything through a VPN connection back to the house and honestly, I don't see myself needing to interface with the switch much after I get it set up. If the cloud dashboard is the only difference then I'll just save the $45 and get the CBS model.

But I wanted to ask you all if there's something else I'm missing that might make the Catalyst a better choice?

Thanks!--

Hey all,

I'm looking to build a small half rack server set in my house and was wondering if there were any tools that let me build out a solution? I'm worried I'm going to forget something and just wanted it all listed out as I think of things.

Yeah I can probably build it out and keep track of it in Obsidian or Excel or something, I was just curious if there were server builder tools like there are PC builder tools?

I mainly want to make sure I get a rack big enough for the few pieces I want to put in it as well as I want to try to calculate the power draw and BTU output which I imagine will be pretty minimal. I just would like hard numbers to know for sure.

Thanks!

Hello all,

I'm deploying an Amazon EC2 instance of RHEL and attempting to install MongoDB via yum.

Following the guide provided by MongoDB, if I place only the repo file for either mongodb 7 or 8, the install fails. If I place both repo files, it still fails.

If only 7's repo file is present, it fails with 7's GPG key.

If only 8's repo file is present, it fails with libssl and libcrypto errors:

Excerpt:

[...]
 - cannot install the best candidate for the job
  - nothing provides libcrypto.so.1.1()(64bit) needed by mongodb-org-server-8.0.0-1.el8.x86_64 from mongodb-org-8.0
  - nothing provides libcrypto.so.1.1(OPENSSL_1_1_0)(64bit) needed by mongodb-org-server-8.0.0-1.el8.x86_64 from mongodb-org-8.0
[...]

If both 7 and 8's repo file is present, it fails on 7's GPG key again.

I've tried manually importing both 7 and 8's GPG keys with:

rpm --import "https://pgp.mongodb.com/server-8.0.asc"

and

rpm --import "https://pgp.mongodb.com/server-7.0.asc"

The 8 import seems to work but the 7 import fails.

The thing is, last week, I successfully installed MongoDB on RHEL 9 using these exact same steps. I'm just doing it again now to capture documentation for work and it's failing.

So my questions are: What the hell?

Seriously though, what can I do to fix this? Is this a problem with MongoDB? Do they need to update their keys?

Thanks
