Anyone got a good resource on SSD vs. spinners in a small server? I'm provisioning a small server to run a number of containers, think intranet, Linux mirror, network monitoring etc. I need stability and longevity above all, not huge read or write speeds. My instinct is 3x SSDs in a RAID5, but I'd love to hear any thoughts. My boss is a really good guy but a little stuck in 2005 at times. We're a Dell shop, by the way.

Is there a simple SaaS issue tracker that'll let my users authenticate with their Google G Suite Basic accounts? Me and my partner-in-crime have been using Github's Issue tracker for a few months, and that functionality would be perfect, but I'd rather not maintain Yet Another Account System.

MF_James posted:Some and experience is about 3-4 years old. Potato Salad posted:hail satan actually I like them compared to a few others, if only their management/patching plane wasn't obviously stapled together over 10 years) Cool! So first let me say that I'm not married to Wyse, but we are a Dell shop, and so far it looks like they could work. The problem I'm trying to solve is that, currently, we have about a dozen "workstations" which are Dell SFF PCs of various vintages running Linux, that basically act as a glorified X canvas. User starts a terminal, immediately sshs to more powerful server. Same with most other programs. In fact, I don't think my users are smart enough to distinguish between, say, a browser window running locally and one running on the server. This is, obviously, a medium pain in the rear end, so I got the idea of scrapping them all and getting some thin clients to hook up to a VNC server. It's very local, the thin clients would literally have gigabit connection and sub half milisecond latency to the VNC server. I realize most people hook them up to Windows or something, but I do see in the docs that they support VNC.

Potato Salad posted:VNC is a little painful. out of curiosity, what kind of budget are you looking at Hahahahahaha...... No, seriously, the thin clients themselves, obviously, and then I don’t think we’re above throwing down some coin for NoMachine, RealVNC or similar. We’ve been getting by on whatever the stock, free VNC server in CentOS is, so far.

Potato Salad posted:is this is the kind of environment where there is zero willingness to pay licensing fees, so you require as good a free solution as possible? Not zero willingness, we’ve specifically discussed buying a commercial vnc server if it benefits performance. That being said, we’re pretty strong on FOSS (sometimes to a fault.) Yes, we have a pretty solid FreeIPA setup.

We use it for archiving, as we have fairly massive amounts of data. Also, we're afraid of the  Currently we have a Dell PowerVault 114X with dual LTO-7 decks. Looking to upgrade to LTO-8. I'd like to wait for LTO-9, but it seems like it's delayed at least until the end of this year, and if history repeats itself, there'll be massive media shortage for the first six months after launch.

MustardFacial posted:Why are you talking to support? Just go to their support website and punch in the service tag. It'll let you download all of the firmware updates you want Usually, yes, but this switch runs OS10, which is locked inside Dell Digital Locker. I think the problem is that the switch was formally not sold to us, but to our vendor, and that has not been fully corrected yet. It kinda shows up on our account, but nowhere to download firmware. Edit: PM'ed you the service tag, would love to be proven wrong.

MustardFacial posted:I tried grabbing it with my Dell Digital Locker account but it wouldn't show up. Now whether that's because the switch doesn't actually belong to me is another matter. Thanks for the effort. I've finally managed to raise enough of a stink with the vendor to agitate the chain of like 6 persons to actually do something other than email the next, and I have hopes something's happening. What's so loving secret about OS10 that they can't just make it available for download.

Today, our servers lost contact with our main storage node. Because I had been migrating the DHCP server. And said storage node pulled an IP (fixed via MAC) from the DHCP server.

DHCP is for having more clients (that come and go) than IPs, or for ease of setup. We have (MAC reserved) DHCP entries for boilerplate stuff (compute nodes, workstations), but we only use it to establish identity upon install, then fix that IP for the life cycle of the installation.

MustardFacial posted:network devices, iDRAC's, UPS NIC's etc generally go into dedicated mgmt vlans with a subnet of appropriate size (/27, /28 something like that depending on the number of devices) IMO. Outside of that you have things like printers which will both print and have a management page on the same IP, so there is very little you can do about that. Agreed. One shop I worked at had a storage VLAN, a general VLAN, a management (iLO in this case) VLAN and a BOOTP VLAN. That was a lot of cables. And expensive in 10G switch ports.

The worst is also users who jump straight to conclusions and tell me what to do/install/upgrade/change. Without even making a proper description of the problem. What were you trying to do? What did you expect would happen? What happened instead? What are the steps someone else could perform to replicate the problem? It sounds so simple yet people are so dumb.
