Swapping Drive To Another RAID Controller
-
@brianlittlejohn said:
Yep, every card is different.
What about if the H310 died and I was replacing it with another H310. Would that be plug and plug, or still test and see?
-
@BRRABill the fact that it's RAID1 makes this simpler, so even if the card fails to recognize the old config, you still have backups and can create a new array.
-
It's always a craps shoot when you are messing with arrays. Sure it's suppose to read the config from the drives and ask to import, but who knows. When the card died, whose to say it didn't take the config on the drive out?

Should work fine. The controllers are designed to migrate the configuration in this way.

OK, for giggles I will give it a try and see what happens.
-
Worked with no issues. Not even a beep.
Now, I assuming if I had gone with a non-DELL controller, there would have been issues? Or can all cards read the same info on the disk? Is it a standard?

One "small" issue I had. (And this might lead to some nice hard drive speed discussion.)
I have 2 7200RPM SATYA drvies in there in a RAID1 array.
On the H310, I ended up with the following speed results:

When I put the H710 and re-tested, I got the following results:

QUESTION1: What would a normal speed be for these drives? Is this in the expected range?
QUESTION 2: Does the 184 seem like a fluke here?

I haven't heard of anyone actually trying this, but Dell just uses re-branded LSI controllers. Don't know how much firmware customization they've done, but I'd bet the drives could be moved between Dell and LSI controller cards.

Yes this surely would go into the "don't try at home" category, I think.

For sure.

Yes this surely would go into the "don't try at
homework" category, I think.Fixed it for you.

I was about to say... more like "only" try this at home.

Oddly enough, when I do the same test on the same drives, on the "E" partition (which is located on the same RAID array as the "C" partition), I get the following results:
Sequential Read (Q= 32,T= 1) : 109.597 MB/s
Sequential Write (Q= 32,T= 1) : 104.111 MB/s
Random Read 4KiB (Q= 32,T= 1) : 1.924 MB/s [ 469.7 IOPS]
Random Write 4KiB (Q= 32,T= 1) : 1.498 MB/s [ 365.7 IOPS]
Sequential Read (T= 1) : 106.960 MB/s
Sequential Write (T= 1) : 105.491 MB/s
Random Read 4KiB (Q= 1,T= 1) : 0.661 MB/s [ 161.4 IOPS]
Random Write 4KiB (Q= 1,T= 1) : 1.243 MB/s [ 303.5 IOPS]Test : 1024 MiB [E: 52.6% (183.0/348.1 GiB)] (x5) [Interval=5 sec]

Interesting tidbit you may or may not know. (I am sure you do.)
While the H310 DOES support single drives non-RAID), the H710 does NOT. You can use a single drive by creating a single member RAID0 array.
Not that you wouldn't always use RAID in a server. Just thought that was interesting.

Good to know with my predilection for software raid, in that specific usage case an H310 will be just fine should I need another HBA.

After being a member here at ML, I have sworn off the H310.
Going to sell mine on eBay rapido!

That's actually standard.

It's perfectly good if you don't want any hardware RAID from the controller
