    Clarification about Norco C-8087-8088F & connection to host

    Hi everyone, I will attempt to build a DIY DAS enclosure and among the components I am looking at is the Norco C-8087-8088F. I have a few questions: 1. This does not seem to require any external power. Is it practically 2 male>female adapters glued to each other? 2. In the host side (my PC) I...

    Bad HBA, Expander, or User?

    I've been running FreeNAS on an old HP Microserver for years now, and I finally decided to upgrade to something more "heavy metal". I'm just now starting to come up to speed on this type of hardware, so forgive me if I'm missing something obvious. I settled on an HP DL380e G8 with the 12-bay...

    Culprit: slightly bad LSI card - was: SC847 45-bay JBODs rear backplane issues - anyone else?

    Edit / Conclusion: These errors were intermittently being logged against drives in a SAS expander JBOD for writes only due to a mostly good, but partly bad port on an LSI SAS9206-16e card running IT mode P20.00.07 firmware: mpt2sas_cm1: log_info(0x31120303): originator(PL), code(0x12)...

    Powering a PCI-E SAS expander without a PCI-E slot? Theoretically possible to make an adapter?

    Hi all I'm thinking of adding at least one SAS expander to my setup, as I am currently using 4 x LSI cards - and therefore 4 x PCI-E 2.0 slots - to run 28 x 2TB SATA3 drives. I know that I can put more drives on fewer cards without losing performance, but as I have a low-profile case I can't...

    I'm new to this JBOD thing so bear with me.. Planning to build gigantic Media server running Ubuntu. I just bought 1 HP SAS expander and an IBM M1015 SAS Card which has 2 SFF8087 ports, meaning it can hold up to 2 SAS expanders... I've measured the mobo and it looks like 2 SAS expander could...

    MPIO expected results? SAS different to iSCSi

    Hi, Using a dual backplane JBOD (SuperMicro) and server 2012R2, what is the expected result of enabling MPIO on SAS disks? I have a host with iSCSi and SAS initiators, both with dual paths (two networks for iscsi & dual port HBAs to SAS drives in JBOD), however, MPIO appears different between...

    SOLD OUT, but ping seller for damaged units $120 shipped HP 761879‑001 12GB SAS3 Expander Card

    HP 761879‑001 12GB DL380 Gen9 SAS Expander Card This is a steal for the new SAS3 expander from HP, which conveniently uses SAS2 cables, so you don't have to buy all new cables! Unlike the old HP SAS expanders, all 36-ports are internal, but like the old one it needs PCIe power. I got one for...
