    Kind of. They will be multiples of 4. Let’s say you got a gigantic 8i8e card, albeit unlikely. That would (probably) have 2 internal and 2 external SAS connectors. Your standard breakout cables will split each one into 4 SATA cables (up to 16 SATA ports if you used all 4 SAS ports and breakout cables), each running at full (SAS) speed.

    But what if you were running an enterprise file server with a hundred drives, as many of these once were? You can’t cram dozens of these cards into a server, there aren’t enough PCIe slots/lanes. Well, there are SAS expansion cards, which basically act as a splitter. They will share those 4 lanes, potentially creating a bottleneck. But this is where SAS and SATA speeds differ- these are SAS lanes, which are (probably) double what SATA can do. So with expanders, you could attach 8 SATA drives to every 4 SAS lanes and still run at full speed. And if you need capacity more than speed, expanders allow you to split those 4 lanes to 24 drives. These are typically built into the drive backplane/DAS.

    As for the fan, just about anything will do. The chip/heatsink gets hot, but is limited to the ~75 watts provided by the PCIe bus. I just have an old 80 or 90mm fan pointing at it.




  • I don’t want to speak to your specific use case, as it’s outside of my wheelhouse. My main point was that SATA cards are a problem.

    As for LSi SAS cards, there’s a lot of details that probably don’t (but could) matter to you. PCIe generation, connectors, lanes, etc. There are threads on various other homelab forums, truenas, unraid, etc. Some models (like the 9212-4i4e, meaning it has 4 internal and 4 external lanes) have native SATA ports that are convenient, but most will have a SAS connector or two. You’d need a matching (forward) breakout cable to connect to SATA. Note that there are several common connectors, with internal and external versions of each.

    You can use the external connectors (e.g. SFF-8088) as long as you have a matching (e.g. SFF-8088 SAS-SATA) breakout cable, and are willing to route the cable accordingly. Internal connectors are simpler, but might be in lower supply.

    If you just need a simple controller card to handle a few drives without major speed concerns, and it will not be the boot drive, here are the things you need to watch for:

    • MUST be LSi, but it can be rebranded LSi. This includes certain cards from Dell and IBM, but not all.
    • Must support Initiator Target (IT) mode. The alternative is Initiator RAID (IR) mode. This is nearly all, since most can be flashed to IT mode regardless
    • Watch for counterfeits! There are a bunch of these out there. My best advice is to find IT recyclers on eBay. These cards are a dime a dozen in old, decommissioned servers. They’re eager to sell them to whomever wants them.

    Also, make sure you can point a fan at it. They’re designed for rackmount server chassis, so desktop-style cases don’t usually have the airflow needed.




  • Solomon Peña was sentenced to 960 months in prison for orchestrating a politically motivated shooting spree and plotting to murder witnesses to obstruct justice.

    […]

    Peña recruited Jose Trujillo and Demetrio Trujillo to carry out a series of shootings at the homes of several public officials. Peña provided cash, instructions, and addresses, and personally participated in one of the attacks. One of the shootings involved a fully automatic machine gun. Multiple rounds struck areas of the homes where children had recently been or were sleeping.

    Following his arrest, Peña attempted to have Jose and Demetrio Trujillo murdered to prevent them from testifying, offering fellow inmates money and a vehicle in exchange for their deaths.

    On March 23, 2025, a federal jury found Peña guilty of all counts of the indictment, including conspiracy, being a felon in possession of a firearm, four counts of intimidation and interference with federally protected activities, four counts of using or carrying a firearm during and in relation to a crime of violence, and three counts of solicitation to commit a crime of violence.

    80 years seems pretty reasonable for everything. I would argue there should’ve been charges for terrorism, but I know that’s more complicated than it should be.


  • I did this back in the days of Smoothwall, ~20 years ago. I used an old, dedicated PC, with 2 PCI NICs.

    It was complicated, and took a long time to setup properly. It was loud and used a lot of power, and didn’t give me much beyond the standard $50 routers of the day (and is easily eclipsed by the standard $80 routers of today). But it ran reliably for a number of years without any interaction.

    I also didn’t learn anything useful that I could ever apply to something else, so ended up just being a waste of time. 2/10, spend your time on something more useful.


  • It won’t officially work, but it’s not too hard to get it going. I just moved a similar box to 24H2 LTSC.

    OP, you’ll probably need to run “setup.exe /product server”, or follow a recent guide. You’ll also need to do this for every major upgrade (i.e. yearly)

    I agree though with the plan to use this as a test ground. I also recently upgraded a Lubuntu system to similar specs, and it runs pretty smoothly. But learning Linux takes a lot of time they don’t have.
