How many Raids can I have on Storage Controller HP Smart Array P420i/1G ?

[Hocke]

I have a HP proliant ML350P Gen8 XE e5-2630 2.3-15mb server with  Storage Controller HP Smart Array P420i/1G !

For the moment I have 2 raids with 3 disk in each and I want to add a third raid with raid 4+0 (4disks) on the same Storage Controller!

The manual says: SAS SATA storage with RAID 0/1/10/5/6, but Im not sure how to read that correct

Can I add a third raid 4+0 (4disks)  and use the same controller?

The question is how to do this.

The ML350p Gen8 has either a 6 disk LFF or 8 disk SFF cage.

Fir connecting up to 3 cages into this server, you need to "expand" the SAS connections. In earlier server models there was a sas expander card used, but here you need optional expander disk backplanes to connect like this:

(the user guide has all information)

You can have up to 24 sff disks installed, the controller can manage up to 64 logical drives, if a cache module is installed.

Logical Drives Supported Zero Memory for embedded controller supports up to 2 logical volumes

512MB cache and greater, Up to 64 logical volumes

Thanks for the reply!

Now I have 1 cage with 2 raid in!

I only need add 1 more cage for the third raid, if I only use 2 cages, do I need optional expander disk backplanes?

You need cage and backplane (as a kit), see the user guide!
