Network cards

All HP workstations include one or two integrated network interface controllers. The HP Z1
Workstation includes a PCI Express Mini Card that implements both wireless LAN and Bluetooth. The
iwlagn driver supports the wireless LAN; in most distributions, the Network Manager automatically
senses that wireless networks are available. Bluetooth support is also available in many Linux
distributions.

Hyper-Threading Technology

The Z Series workstations support Hyper-Threading Technology (HTT), an Intel-proprietary
technology that improves processor performance through parallelization of computations (doing
multiple tasks at once). The operating system treats an HTT-enabled processor as two virtual
processors and shares the workload between them when possible. This feature requires that the
operating system support multiple processors and be specifically optimized for HTT.
To enable HTT:
1. During startup, press
and select options.
2. Select Advanced > Device Options.
3. Set Hyper-Threading to Enable, and then press
4. Select File > Save Changes and Exit.
5. Restart the system to enable HTT.
NOTE: On most recent Linux distributions (including RHEL 5, RHEL 6, SLED 11, and updates to
those streams), the kernel automatically detects that HTT is enabled and works correctly.
