NOTE: Windows Storage Server 2012 supports the use of BitLocker on clustered volumes. For

more information, see the “BitLocker Overview” article on Microsoft TechNet at:

If encryption is required, the Encrypting File System (EFS) is supported on clustered volumes. For

more information on EFS, see the following Microsoft article:

Networking options

The large number of network adapters on each server in the HP StoreEasy 5000 Storage provides

a number of different options for networking. The network adapter named "Cluster Internal" is

pre-configured as a private cluster heartbeat and should be left as is, but all other adapters are

available for use. Use the guidelines below as an aid in making configuration choices.

Network teaming

Network teaming is a common use of multiple network adapters. Teaming is used to increase

available network bandwidth and provide fault tolerance. Teaming can be across multiple ports

in the same network adapter or across network adapters.

Multi-home

Distributing network workload across multiple network adapters is also commonly used. Placing

each network interface on a different subnet allows the workload on each subnet to be serviced

in parallel rather than through a single interface.

Dedicated networks

Implementing a unified storage solution requires that different protocols be used to access a storage

system. In one instance, a block protocol like iSCSI is used to present storage to a virtual machine

host. At the same time, a file protocol like SMB is used for sharing files for department or user

home directories. A dedicated storage network for each protocol allows the network traffic to be

kept separate to maximize performance. Similarly, one network interface can be used for system

management and monitoring while another interface can be used for data traffic.

10 GbE versus 1 GbE

Other than the obvious difference in speed, 10 GbE provides an order of magnitude difference

in lower latency. Lower latency is ideal for transactional database applications and virtualization.

Combining a 10 GbE dedicated storage network for a virtual machine infrastructure, and a 1 GbE

network for shared folder, takes the most advantage of the network offerings. A classic example

is thin clients whose resources are hosted on virtual machines (for example, the Citrix model).

Unused network interfaces

Disable network interfaces that are disconnected or will not be used to prevent configuration issues

and extra health monitoring alerts.

Using Server Core

The Server Core interface is a command prompt with PowerShell support. In Windows Server

2012, you can transition between Server with a GUI mode and Server Core mode without

reinstalling the operating system.
