SAS disk controller (RAID 0/1/5/10 compliant, 1 GB battery backed cache)	SAS disk controller (RAID 0/1/5/10 compliant, 1 GB battery backed cache)
Monitor (17” LCD/LED or larger)	Monitor (19” LCD/LED or larger)
1 Gbps Ethernet interface	1 Gbps Ethernet interface

Microsoft Windows 2012, 2016 Remote Desktop Services Client Access Licenses	Microsoft Windows 2016 Remote Desktop Services Client Access Licenses
Citrix XenApp 7.x or newer concurrent user licenses*	Citrix XenApp 7.x or newer concurrent user licenses*

Note: *Microsoft Remote Desktop Services licensing and configuration is required regardless of which remote environment user interface (Microsoft or Citrix) will be used. If Microsoft RDS will be providing the remote environment user interface, Citrix XenApp licensing is not necessary.

Note: If a multi-server farm will be used to provide support for remote desktop, it is recommended that the administrative services of Microsoft Remote Desktop Services or Citrix XenApp be located on a separate server from those servicing remote user sessions.
