You can buy any sort of controller you want that is supported, SAS, SATA, SCSI, USB, eSATA, or even fibre channel. Add external drives to an external enclosure. &nbsp; But if you want the disks to be part of that RAID set, you need to plug the drives into he PERC6i. &nbsp; It doesn't matter if the disk is internal or external. &nbsp;The controller doesn't care.

No. I want to plug it in the ONE available caddy slot.

I have a PowerEdge T310 with 3 hard drives in there in a RAID5 (250GB each). I need more storage. It uses a Perc 6i Controller.<br />

Can I use the fourth slot to add a hard drive outside the RAID? I need more storage. Or is there an easy way to create more storage within the RAID?

How to add more space to a T310?

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.
