Hi,

Karlo is right that you can't mix them in same logical drive, but you don't want to, so you can do this - one RAID5 with SATA HDDs for data and OS on separate log drive

Re: Mount a Main HP SAS drive and a Raid5 with common Sata Disks

I mean just one SAS disk for the OS; and on the other size, a Raid5 with four SATA disks.

I have another doubt... I have seen that the model I want comes with a tower, does it come with both 2.5 and 3.5 boxdisks, the model I am interesting is ML 350G5 458246-421, it seems that just cames with 2.5 boxes... I need this tower but with 3.5 hd-boxes...

- does it come with both 2.5 and 3.5?
- if so not... could I order the tower with 3.5 box?

An another question more... now you know the model I want... (by now just SFF) can I plug in here an HP SAS 3.5 inside it (I am not interesting in this disk has hot plug) just to save money and install on it the SO (as a main disk)

Or the third possibily....

One SATA 2.5 disk for the operating system...
and four SATA 2.5 disk for the Operating System... (using for example Samsung or Seagate brands....)

hi

well SFF is your decision...

usually recommendation is RAID 1 for OS and RAID 5 for DATA.

But it is OK if you considerer that reinstalling your OS it is not difficult an you have your backup up to date you can use RAID 0 for your OS.

as you saw in another thread there are SFF models and LFF models and cages can not be mixed.

about your Seagate / another HDD brand it is up to you they can work they can not

Re: Mount a Main HP SAS drive and a Raid5 with common Sata Disks

Hi,well,the question is that I gave prices to a client with this model but with a SAS HP disk 3.5, and four Standard SATA disks (not HP disk), and know the computer just has SFF disks...

So I would like to solve the problem without "more" money...

1- Is there possibilite to know compatible SATA disk 2.5 of other brands... have you know other "common" brands thas work with this server ???? Is not there a HDD compatible list ???
