Device Support 256 Non-RAID SAS/SATA devices
Integrated RAID (IR) 14 spread across 2 volumes
RAID 0 10 per volume
RAID 1 2 per volume plus hot spare
RAID 1E 10 per volume
RAID 10 10 per volume
Per Port-Multiplier.lockdoc schrieb:Wie kann ich denn bitte 256 devices daran anschliessen?
Laut LSI [1] gibt es eine "IT"-Firmware, die ihn zum normalen HBA ohne RAID degradiert.lockdoc schrieb:Ich finde nirgends was von JBOD oder pass-thru, kann man den auch ohne RAID fuer den Einsatz im ZFS betreiben?
Das waer super!vom 9211-8i kann ich die tage berichten
Amenraid auf dem controller ist vollkommen ueberbewertet.
This driver provides the CAM(4) subsystem with native access to the SATA
ports of several generations (Gen-I/II/IIe) of Marvell SATA controllers.
Each SATA port found is represented to CAM as a separate bus with one
target, or, if HBA supports Port Multipliers (Gen-II/IIe), 16 targets.
Most of the bus-management details are handled by the SATA-specific
transport of CAM. Connected ATA disks are handled by the ATA protocol
disk peripheral driver ada(4). ATAPI devices are handled by the SCSI
protocol peripheral drivers cd(4), da(4), sa(4), etc.
So also ich habe gerade den PCI-e DAWICONTROL DC-324e RAID ins Auge geworfen.

und wozu raid auf dem controller ? ich habe doch zfs.
raid auf dem controller ist vollkommen ueberbewertet.
Jetzt sagt mir wikipedia allerdings, dass JBOD zweierlei Dinge seien koennen:
Man sollte nicht alles auf Wikipedia einfach so glauben. JBOD bedeutet, dass die Platten vom Betriebssystem verwaltet werden, also kein RAID0.

Der Bär hats sowas mit Supermicro X8DT3-F Board, 2x X5670er Xeonbären und 12x 16384 MB DDR3 (ECC reg.) am Start. Als ZIL Cache werkelt von STEC die ZeusRAM SSD mit 8 GB. Bestückt ist das ganze mit 24 Stück SAS II Seagate Constellation ES 3,5" 7.2k Platten. Als Controllbär werkelt ein Arecabär der sich en Wolf schuftet und die Datenbärchen "ausführt".
