NEW LSI 9300-16i 12Gbps SAS-3 PCIe x8 HBA P16 IT mode ZFS TrueNAS UNRAID (WHL #94)

Here’s a quick and simple one: Cooling advice for 16-port SAS cards.

The LSI 9300-16i cards have gotten surprisingly cheap over the past months. Dirt cheap, in fact. All-16 port SAS cards are traditionally pretty pricey, even though they are “just” two 8-port cards on one PCB. In the past 10, maybe 15 years, there was never a time when buying a 16-port card (used or new) was cheaper than buying two 8s. Sure, sometimes people needed a single-card solution (availability of PCIe slots, PCIe lanes, or space in general), but the usual recommendation for 16-bay chassis like my Supermicro 836 was always to buy 2×8 instead of 1×16.

The strange formatting of Oracle-branded HGST SSDs (WHL #71)

A little tale from the world of enterprise computing (again). Well, I needed something to do alongside filing my taxes, and I recently received a bunch of hardware, so there’s that.

I ordered, after long and unfruitful discussion and some eBay detour that also didn’t work because of, well, eBay, a couple of replacement hard disks of the spinning rust type, as well as SSDs to support them. The original ZFS RAID volume that kept *ALL* my data crashed via some obscure file system bug, and since I’m not a paying Oracle customer (not that they would help me out – everything is plastered with “restore from backup” notes), I finally migrated to Ubuntu and OpenZFS.

Not-so random thoughts on LSI HBAs again (#P34F1)

A couple months ago I scraped on the surface of the topic of LSI debranding/crossflashing. Now’s a good time to visit that again, since I got another branded LSI card that I wanted free of the manufacturers old firmware and the “hey look at meeee, I’m a veeeery special controller” look in any device tree. Yes, we know you’re special, but the annoying kind of special. You’ve likely been the default card in tens of thousands of servers or the only (supported) choice people had when opting for external SAS. […]
