I want to buy a Hp Proliant ML350G6, this server comes with the Hp HP SMART ARRAY P410I (RAID 0,1,1+0), I don´t want to use Hot Plug SATA drives, I just want to use non hot plug sata drives, can I use 4 non hot plug sata drives of 2TB each?, how are they connected?, if I cannot, can I buy 2 hot plugs SATA drives of 250GB for the operating system, and then buy another RAID controller for installing 4 non hot plug of 2TB with RAID (0+1) for use of storing company files??...

You don't have to use the RAID features but the drives are 2.5inch and install in an enclosure at the front of the server.  This makes them hot-plug.

The Smart Array is on-board AFAIK so the enclosure connects directly to it.  There are also additional RAID controllers that you can add to the server, so there must be a way of adding different drives to the system.

If I buy 2.5" drivers, will I be able to connect them to the P410 controller with an normal SATA cable?

Portable, direct connect server access

The ATEN CV211 connects a laptop directly to any server allowing you instant access to perform data maintenance and local operations, for quick troubleshooting, updating, service and repair.

Do I need a special caddy?, or a special converter to connect them to the SATA raid controller?

I am afraid you have to stick with officially supported configuration of disk drives against particular RAID controller. I would NOT recommend you buy any RAID controller yourself, because this might lead to problems - instead use only HP certified and preconfigured RAID controllers.

General rules:
- if server housing is constructed with hot-plug cages, then officially supported are only hot-plug disks
- if server housing is NOT equipped with hot-plug rails, then you may open the housing and add as many disks as there are free SATA/SAS connectors and power supplies

According to link you supplied, your RAID controller supports hot-plug and non hot-plug drives, but as I say, phisically mounting NON hotplug disks is a problem if you have hot-plug cage in server housing. If not, then your configuration should be OK.

The correct link for the server I want to buy is: http://h18004.www1.hp.com/products/quickspecs/13241_na/13241_na.html

This is the server image:
 ML350G6
I still can mount the 3.5" below the DVD drive, but I don´t know if the server has the correct connectors.

Hi,

buying 4 generic 2TB disks and 4 hot-plug rails (the ones you gave the link) would theoretically work. But you NEED to buy generic disks with hot-plug SATA +POWER connector, which might or might be not present on evey generic SATA disk.
As I read your documentation on given links, only Hot-Plug compatibility is supported, so your red line is Hot-Plug! Buy hot-plug (generic) SATA or SAS disks, with or without cages (...and buy hotplug cages separatelly, as you said - YES they would fit).

But generally, I don't get it - for example, we are partners with FUJITSU and each and every server we sell is suited to meed customer's specifications, manufactured and tested in factory, with properly sized disks etc. Customer gets 3-5 year warranty on-site for all parts, and such a server is not more expensive vs. home-made variant.
So my reccomendation is to contact HP dealer, and order properly configured server.

If you intend buying cheap SATA drives meant for desktops it'll end in tears, they'll keep dropping off the RAID controller because every time they go into deep recovery to try to read a dodgy data block the controller will drop them from the array, they'll also burn out probably as they're not designed for 24x7 opperation.
