I am putting together an ICX6610 stack of several switches, I want to use the 40G QSFP+ ports for this. Half of those ports are apparently permanently configured as native 40G ports and half of them are 4x10G ports. My understanding is that passive DACs don't really care about one type vs the...

I just thought I'd post this in case anyone is interested about the airflow direction in the ICX-6610/6650 power supplies and fan modules: Both the fan modules and the power supplies of the 250W/non-PoE switches use the same fan model numbers for each respective module, just installed with the...

Well, I'd deleted my post because you'd followed up while I was writing it, and got it to work which, um, OK, makes it all the stranger. They could have just moved the USB connector to the back, which is completely blank on these, used a stacked pair of rj45s in the front and any typical network...

Well, put in a low ball best offer on (5) 6610-24F-Es that was accepted so I should have a full set of front to back 250W power supply and fan modules for the non-PoE 6610s and the bare 6650 switches, I've bought. All should show up at roughly the same time(ish).This seemed like the best place...

Another question I have is in regards to the airflow direction of the 6610s. Seems most PoE switches for sale are configured as front to back (E models), and most non-PoE switches are back to front (I models). I guess this makes sense given that PoE switches would typically be closet switches...

I have been using Aruba S2500s in my house for quite some time, like at least 1 in every room, and, well kind of a lot of them in a few rooms, mostly because the number of 10G SFPs you net out of one of these is 2 if you ring stack them. I want to move LOTS more over to 10G so looking to replace...

Well yea, Supermicro IPMI requires java too, as do an awful lot of the VM consoles, so I'm kinda OK with it being Java. It's mostly a BIOS/EFI/Boot access thing, or maybe a way around a stuck NIC. Anyway good to hear they're usable, I read somewhere that some of the other IP KVMs were bricks...

Used Raritan Dominions have gotten cheap, or maybe they always were, I wasn't really looking, but seems like <$200 and often <$100 for multi-user KX2s. So are there any gotchas to these? I know you need the cat5-to-breakout dongles for these, but those seem to be gettable pretty cheap as well...

Yea, I haven't read anything to suggest otherwise. It's always good to ask though right? I think the DRi and DR3 might even use the same BIOS. Looks like the big difference between the 2 is that I have twice as many useless SAS/SATA ports (well in IllumOS anyway, the SCU ports are not supported...

Hmm, interesting I had a similar issue with a Seagate ST2000LM007, I had one drive that reported like 10% less capacity than many others. It also reported different firmware although all the same revision numbers for everything else. In my impatient attempt to cut to the chase, I had a flakey...

Yea I have pretty much these same questions. The built on Optane buffered NAND devices, from my understanding, are meant to be OEM only devices for laptops, and my assumption would be that they are essentially like the 16 and 32GB caching devices that just so happen to also have some NAND on the...

The Icy Dock cages are pretty much just passive boards. The one exception being that they are essentially 5V exclusive devices, they use 12V but only for the fans, the 3.3V is omitted on most models. So if there is any 3.3V reliant circuitry on the drive or feature that probably won't work. Like...

The only issues I've ever read about involve intermediate passive components in the middle that do not adhere to the negotiated specs of the end points. So connecting a PCIe v4 slot to a PCIe v4 capable card with a PCIe v3 rated riser cable. So in your case, I guess that would be either the SFF...

Seems like the place to ask this, so I am looking to use an Optane P4801 100 GB M.2 on a Supermicro X9DR3-LN4F+ and also on another box with an X9SRL-F, in both cases I would be using a PCIe (V3) x4 slot with just a run of the mill PCI to single stick M.2 NVMe adapter, specifically an ECM26 from...
