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.

JMB363 2 Port PCI-E SATA II 2.0 RAID & 1 IDE 3.5″ to PCI Express Adapter Converter Card Expresscard (WHL #67)

Time-incorrect retro computing time! We’ve had a lot of computer-related stuff recently, but this one is an elegant mix of old, niche and Wan Hung Lo. It’s perfect.

First of all, what is it? It’s a PCI Express 1.0 x1 card with (according to Wikipedia) the only native PCIe to PATA and SATA interface chip there is, a JMicron JMB363. The “confidential” three-page datasheet floats around on the interwebs if you want to take a look. PCIe 1.0, AHCI and IDE compatible, HotPlug, NCQ, UDMA6 = ATA133 (1 port, so 2 devices), SATA2 (3 Gb/s and 2 ports, so 2 devices as well), RAID 0/1/0+1/JBOD functionality. […]
