CentOS - Sep 2020 - Question regarding cent OS 7.8.2003 compatibility with large SAS disks

Hello,

I have a blade server with SAS HDD's of 12TB in total.
3 HDD's of 4TB each.

Is it possible to install Cent OS  7.8.2003 on 12TB disk space?
I will be installing Cent OS on the bare metal HW.

I referred = https://wiki.centos.org/About/Product
But slightly confused with the 'maximum file size' row for ext4 FS.

Thanks & Regards,
Amey.

I have done it numerous times.

That's not a problem at all. In the server world, 12 TB is actually
fairly small. :)

Thanks Digimer & R C for the quick help.

I am going to touch the blade servers after a gap of decade hence I
was in doubt :-)
The Cloud computing era has wiped my knowledge about server HW & OS
compatibility :-/

Hi,

We have servers with 500 Tb in line with SAS attachment on a SAN without any
problem!

It?s perhaps a firmware problem with your SAS card, no?

the SAS hardware has to be SAS2 or newer, as SAS1 had a maximum physical
drive size of around 2tb

and the boot volume has to be GPT as MBR has a 2TB limit.

otherwise, sky is the limit, however, what the other guys say, I do NOT put
my OS on my data raids,  its usually on its own mirror of two small drives.

I also tend to avoid "hardware" raid cards, and prefer HBA cards that
present the drives as plain SAS devices, then use the OS's native storage
management for raid (mdraid + LVM for Linux, ZFS on FreeBSD, etc)..   I
generally spec raid 10 for performance data, and raid 6 or 60 for bulk
data.   raid5 is frowned on these days, disks are so big, and rebuild times
are long enough that the risk of a double failure is fairly high.

CentOS 8 defaults to XFS, not to ext4, so that row has no bearing on your use
case.

Although I wouldn?t recommend overriding this default, if you did, I don?t see
why you?re worried in the first place. 12 TB < 50 TB, the limit for
partitions created by the stock versions of e4fsprogs included with CentOS.
