Virtual TapeServer 6.03.41 Installation Guide

20 | Cabling and Connecting VTS
Cable connection order
Here is a summary of the VTS server configuration:
VTS Model Height
# of
SCSI Buses # of FC Buses
Optical or
Magnetic Drives
VT5900-E 2U 0, 2, or 4 2, 4, or 6 DVD/CD
Four SCSI ports (in slots 4 and 5) and two 4Gb Fibre Channel (FC) ports (in slot 3) are
provided in the base hardware configuration. Optionally, one or both of the dual-port SCSI
cards in slots 4 and 5 can be replaced with dual-port 2Gb FC cards.
Note For the most reliable service, use cables of the highest quality and shortest possible
length based on the location of the equipment in the data center.
The VT5900-E is built on a 2U (3.5 inch) chassis and provides up to four SCSI buses,
numbered 0-3. A dual-channel 4Gb FC card is also provided for connection to external storage
(buses 4 and 5). This base model allows the use of all four SCSI buses for connecting virtual
tape drives (no ports on the 4Gb FC card can be used for virtual connections).
The recommended cable connection order for the SCSI converter attached to a base model of
VT5900-E is as follows:
HVD Buses A B C D
To NonStop
server
To NonStop

To NonStop

LVD Buses A B C D
To bus 0 (PCI-X
slot 4A) on VTS
server
To bus 1 (PCI-X
slot 4B) on VTS
server
To bus 2 (PCI-X
slot 5A) on VTS
server
To bus 3 (PCI-X
slot 5B) on VTS
server
Note When attaching NonStop servers to the HVD buses, it is recommended that you
attach to HVD bus D then to HVD bus C and then to HVD buses A and B if necessary.
Here is an illustration of the slots on the back of the base model VT5900-E (DL385 G2). If the
P800 card is installed (to support the MSA 60), it is placed in slot 3 (below slot4).
