I have a 64-bit system which has both an Adaptec 39160 SCSI PCI controller and a LSI SAS PCI-express controller - there are two SCSI disks (/dev/sda and /dev/sdb) on the Adaptec controller and four on the SAS controller (/dev/sdc, /dev/sdd, /dev/sde and /dev/sdf).
I´m still using an Atom mainboard as my private homeserver. Now i just want do some backup to an Ultrium 3 SAS drive. So i want to get a cheap, out of the Box supported, SAS controller to connect the Ultrium drive. In the past i used the Adapted SCSI controllers and they worked very well.
I am using a usb drive to install Fedora 17 from. The machine has an old Adaptec 29320ALP PCI SCSI card. The installation process starts, but doesn't pick up the drive (single drive, no hardware raid, unformatted, not sure if partitioned) as a target installation drive.
I am trying to read out a pcmcia flash card on my pc. For this purpose I got one of those IDE to PCMCIA adapters. FYI, these adapters don't have any chips on them, just a male IDE socket that connects to the IDE cable and a male type 1 PCMCIA socket that takes the card. Everything slotted in nicely.
I have no idea how to get this running, but this is what I've done so far.
I have a scsi disk with SMART enabled and with the following information:
# smartctl -d scsi -i /dev/sg1
=== START OF INFORMATION SECTION ===
Device type: disk
Transport protocol: SAS
SMART support is: Available - device has SMART capability.
SMART support is: Enabled
I'm running RAID 1 on an Adaptec 6405. I'm trying to decide if I need to install the ZCMP on the card to provide Cache protection. Adaptec's ZCMP is the equivalent of a BBU - battery backup for the cache.
I want to enable write caching on the card to ensure the system performs well.
