Storage
The HP Z840 has an embedded LSI 2308 SAS controller which supports eight 6 Gb/s SAS/SATA ports, and SW RAID
modes 0, 1, and 10. The C612 chipset supports two SATA AHCI controllers, sSATA and SATA. The sSATA controller supports
four 6 Gb/s ports and RAID modes 0, 1, 10 and 5. The SATA controller supports two 6 Gb/s ports and RAID modes 0 and 1.
Ports from both controllers can be routed to the rear panel with an eSATA bulkhead option. Note that it is not possible to
RAID across the two SATA controllers.
The optional HP Z Turbo Drive featuring a PCIe connected SSD is supported on this platform and provides performance
levels greater than 1 GB/s. Up to two Z Turbo drives can be configured in the factory. Data RAID is supported through
Microsoft Windows Disk Manager.

On the front I/O area, the HP Z840 provides four USB 3.0 ports (the top-most supports battery charging), combo headset
and separate microphone connections.
In the rear I/O area, the HP Z840 provides four USB 3.0 ports, two USB 2.0 ports, two gigabit ethernet LAN ports, audio
Line-In, audio Line-Out, PS/2, and a serial port. Additional rear I/O ports can be added via PCIe add-in cards.
