This means you no longer have to use a beta version of SoftRAID if you have upgraded to macOS 11 (Big Sur). You have to waitĪnd the RAID card does the rest.As many of you know, we released SoftRAID version 6 last week. The companies making the soft RAID,ĭon't take the job quite that seriously. Whereas a real hardware RAID cardĬan do that at 2000MB/sec (probably limited todayĪnd real hardware RAID companies, it's their only business.ĭo a good job. If the soft RAID was doing RAID5, then the processor wouldīe asked to XOR blocks of data, using the ALU on the CPUĪnd the XOR instruction. Into a sequence of reads or writes to individual disks.
What is softraid driver#
On a "soft RAID", the driver in the OS does more monkeyīusiness, such as translating 0x1234 and some length field, Using scatter/gatherĭMA lists to load system RAM buffers with data from The OS says "Read 0x1234"Īnd the RAID card does the rest. The XOR step) is all done by the RAID card, without the Pattern (which chunks to read, the interleave order, The advantage of a real hardware RAID, is the transfer You use the "Management"Ĭontrol panel at that point, to set up RAID arrays,Įmail yourself if the RAID array fails, and so on. Once the handoff to the OS occurs, the OS driver talks The "real" hardware RAID allows setting up thingsĪt BIOS level too, just to get around some bootstrapping Or a PERC, can have a BIOS page inserted.

Parts of them "shrink", all in the name of makingĪs much of the 256KB available as possible. The BIOS loads those ROM images, and unnecessary To boot, for the card which is "furthest" from the CPU
