Hi folks,
a knowledge question for HP and Windows server users:
I plan to have a small Hyper-V system based on ML150 Gen9. There will be an P440 controller. Then there will be a RAID 1 consisting of 2 SAS 10k disks, with addtional (third) hotspare disk. This is for data (VMs). Then I plan to have another RAID 1, consisting of two big entry level SATA disks, maybe 4TB each. This is designated as short term repository for backup data (they get duplicated onto USB-RDX drives). Host will reside on USB flash drive.
Question 1: Could these five disks respectively two RAIDs all be connected to and/or handled by P440?
Question 2: If not, could the SAS disks be connected to and handled by P440 and SATA disks connected to onboard SATA connectors and then be treated as Software-RAID1 by Server 2012 R2.
Any HP- and MS-Server specialist who is saddle-fast enough with HP components and MS server technology to put a statement on that?
Thanks and regards,
Stefano

Re: How to connect both SAS- and a SATA-RAID
Hi Stefano,
It is possible to create two different arrays consisting of SAS drives separately and SATA drives separately.
Ensure that SAS drives are in a single array and SATA drives in a separate array.
Press F10 key to start HP Intelligent Provisioning and select HP Smart Storage Administrator and configure arrays from there.

Vijayasarathy

Re: How to connect both SAS- and a SATA-RAID
That's good information, Vijayasarathy. :-)
How do you connect these two SAS disks and the two SATA disks to P440? As far as I see there's only one SAS port on that controller.
Thanks and regards,
Stefano

What server model are you working with? Generally the drive backplane connects to the controller and the drives all plug into the backplane

Thanks for input. It's a ML150 Gen9. Searched through many documents, but could not it out.

Sorry, missed that in your first entry.
I see your pretty much asking the same question in this other thread

Hi folks,
I don't understand the different drive options of ML150 GEn9 systems. Is it possible to get some help from here? So what I would like to achieve is a small Hyper-V 2012 R2 system with
-3 SFF SAS disks on P440 (RAID 1 with hotspare, controller has FBWC)
- mirrored 4GB or 6GB SATA drives for daily and/or nearline backups connected to onboard SATA connectors
- DVD-Drive
- internal LTO-2-Drive on SC11xe for long term backups, stored abroad
I would like to reuse the given LTO-2-Drive, which is connected to an Adaptec 29160 in the old server.
Is such a configuration possible? Do I need any special cages ?
Thanks for sharing your knowledge,
Stefano
To accomplish what you're wanting to do, you need both a SFF and a LFF drive cage. The only way to get the large capacity drives is LFF. When building a CTO system, the 2nd drive cage always matches the 1st drive cage. Should you be able to mix the cage type? Probably, but it isn't a tested and supported configuration.
If you order a base model with the LFF cage, you would then need to purchase the P440 and a 8SFF cage and cable. This would keep the 4LFF cage conected to the embedded B140i
Another option would be to get the P840 controller instead of the P440 and connect both cages to the P840 and disable the embedded B140i
If you look at the maintainance and Service Guide under the Storage Cabling section, you can see how the cables should be connected for backplane power and disk controller
http://h20564.www2.hp.com/hpsc/doc/public/display?docId=c04504829&DocLang=en&docLocale=en_US
Look at the controller and cabling options (and note) on page 24 and 25 of the QuickSpec for the extra parts
http://www8.hp.com/h20195/v2/GetPDF.aspx/c04447843.pdf
P440 requires a cable kit
P840 requires two cable kits and a baffle kit
I need to state again, mixing SFF and LFF cages is not a tested option. For a supported option instead of 3SFF drives, use all LFF drives and two LFF drive cages.

Re: How to connect both SAS- and a SATA-RAID
Thanks for input Jimmy. According to your statements I will simplify the system and use only SATA LFF disks. Since it does make sense to have two RAIDs in a virtualized environment - 1 RAID1 with hotspare for host and guests, 1 RAID1 with slow and big disks for backup - my options now are this:
- 3 x HP 500 GB 6G SATA 7.200 U/min LFF in RAID1 for data (with hotspare)
- 2 x HP 4 TB, 6G, 7200 U/Min., LFF SATA in RAID1 for backups
As far as I understood your statement this should work with one single P440. But when I try to verify this with HP server configurator it throws errors to me. It says I have to use the FIO-Kit (can't find any information about that), that disks in a RAID have to be the same and that the number of disks must be even.
Could you once again help me out of that confusion?
Thanks and regards,
Stefano

SolutionWith a total of 5 disks you will need both drive cage assemblies. The configurator probably wants to use the P840. If you still want to use the B140i for the two larger drives you may just need to run the configurator as a 1 cage configuration and seperately purchase the 2nd LFF drive cage and cable kit along withthe P440.
FIO indicates Factory Intalled Option.

Re: How to connect both SAS- and a SATA-RAID
Ok, thanks. That's great information. I feel much better now with HP's system of options, parts, add ons etc.
