[pabusa]

Hi,can I "mount" a SAS HP drive for the operating system, and a Raid5 with four common SATA disks, do I need anything more to get them hot-plug ??

Please, I would like to know it, and sorry for my english

hi

sorry

I am confused???

you want to mix a SAS HDD with SATA HDDs and create an RAID 5 with all of them?= if so not possible...

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

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)

[pabusa]

And another possibility...

Can I install 5 SATA 2.5 disks in RAID5 and install on it both Data an Operating System...

[pabusa]

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
