I posted a thread on this once long ago[1] -- but we''re still fighting with this problem and I wanted to throw it out here again. All of our hardware is from Silicon Mechanics (SuperMicro chassis and motherboards). Up until now, all of the hardware has had a single 24-disk expander / backplane -- but we recently got one of the new SC847-based models with 24 disks up front and 12 in the

So I'm curious how SAS JBOD arrays and linux MDraid as implemented in CentOS6, and SES (SCSI/SAS Enclosure Services) backplane controllers 'get along' and how much configuration is needed to get the warning lights to work properly. scenario: whitebox server with a SAS backplane or two, daisy chained on a SAS HBA (like an LSI Logic 2008), and disks organized as several raid5/6

So is this Digium taking over Pulver's' void? Same color scheme and fonts.

I have a couple development servers running centos 6.3 64bit that have LSI 9211-8i SAS2 controllers connected to a SAS2 backplane. these work fine with SATA hard disks (populated with a bunch of 3TB SATA drives)... I'm trying to install a OCZ Vertex3 SSD on each of the two servers to do some ssd caching tests... system sees the drive, so I do the following... # parted -a min

During the diagnostics of my SAN failure last week we thought we had seen a backplane failure due to high error counts with ''lsiutil''. However, even with a new backplane and ruling out failed cards (MPXIO or singular) or bad cables I''m still seeing my error count with LSIUTIL increment. I''ve got no disks attached to the array right now so I''ve also

Does anyone have a supermicro 942i server chassis? I'm trying to figure out if it has a true nine 5.25" drive bays, or if the one occupied by the 3.5" caddy is special / crippled. What I want to do is install three of the supermicro 5x3 hot swap backplanes and I'm gunshy about buying one site unseen. Thanks! Gordon

In my experience the mass market HBAs and RAID cards typically do support only 8 or 16 drives. For the internal variety in a standard rack-mount server you'll usually see either 2 or 4 iPass cables (each of which support 4 drives) connected to the backplane. The marketing material you've referenced has a white lie in it: supporting more than 16 drives on a single card is very likely only

Hi, all I've installed Version 3.5.10-0.109.el5_8 from the samba3x RPM for Win7 compatibility. We are predominately a Linux shop and have only a handful of Win7 (Pro/Ultimate) dual-boot workstations for running things like Photoshop, etc We run a fairly minimal LDAP backend for Linux auth/automount (no SASL backend) and have not implemented a full Samba schema - i am waiting to build an

Hello - It's been sooooo long since I've tried hacking the kickstart media to include an updated driver but I guess that time has come again for me at least, getting an updated "igb" driver into the CentOS 5.2 installation for a HP DL165G5p(I'm not ready yet for CentOS 5.3). Anyways, I had a pretty basic question, I added a bunch of entries into the pci.ids file that were

Does anyone know which physical interrupt line out of the four on the PCI backplane the TE405P uses? Or is it somehow configurable by hardware or software? I'm trying to diagnose a problem where the card generates no interrupts in one system, but is fine in another system. These systems are SBC-in-backplane type. My knowledge of how PCI works at the physical layer is rather limited, but I
