Is there a way to update the firmware on the RAID card?

Is there a way to update the firmware on the RAID card?

I have a DL380 G4. Right now it supports RAID 0, 5, and 1+0.

I wanted to see if there's a firmware update for the RAID so it can support more kinds of it. (1,0+1..etc etc)

Re: Is there a way to update the firmware on the RAID card?

You have all the features that you need, raid10 with only two drives is the same as raid1. Raid0+1 is not available and I don't think you want to use raid0+1 ever.

In any case the firmware upgrades do not add any raid features to the card, they fix any bugs or improve performance.

Re: Is there a way to update the firmware on the RAID card?

RAID 6 or what we call Advanced Data Guarding, is available as a license-able feature, and provides similar capabilities to RAID 5 but can sustain more than a single disk failure.

RAID 1+0 is the standard used by SmartArray which offers the redundancy of mirroring with the performance advantage of striping.

An unqualified "RAID 1" essentially implies a performance hit since you don't get the benefits of reads of alternate tracks from alternate drives.

If by RAID 0+1 you mean striping data across multiple drives and then mirroring that set to an identical set, there are no performance or redundancy advantages and it unnecessarily complicates removal/replacement of drives. Old rationales based on parallel SCSI technology of the past have been obviated by more modern approaches.

Re: Is there a way to update the firmware on the RAID card?

apart from above remarks about supported raid, you do not give any details about OS or firmware involved.

but for the question "is there a way to update the firmware"
- go to the support page

- select your OS.
- like for w2k3 there is "Smart Update Firmware DVD "

Re: Is there a way to update the firmware on the RAID card?

The embedded SA on the G4 support 0, 5 and 1+0 (or 0+1).

There has been a few changes in the past 10 years.
In the old days they used to support 0, 1, 5 and 0+1 (Compaq did call stripped mirrors 0+1)

One change was the additon of ADG (RAID 6), but that was only supported on the 5300 and 6400 controller.
On the 5300 it required a ADG enabler.
Can't remember with the 6400.

another change.
They remove RAID 1. Since if you use 2 disk only in a RAID 0+1 or 1+0. You actually got a RAID 1.
That was introduced with the ORCA, if I remember correctly.

Then came the HP - Compaq merger, and RAID 0+1 naming was changed to 1+0. But still the same stuff - stripped mirrors.

With the SAS/SATA Smart Array controllers, you now need BBWC to use RAID 5, ADG and online migration / expantion.

So no. FW upgrade will not add more RAID levels, but it might improve stability.
