HP RX8620-32 - Manual (Page 21)

External LAN—The external LAN port is a 10/100/1000Base-T external LAN port that uses an RJ-45
connector.
External SCSI—The external SCSI port is an Ultra160 LVD external SCSI port for connections to mass
storage or media.
HP Integrity rx7620-16 Server internal peripheral bay
The Integrity rx7620-16 Server internal peripheral bay is located at the top front of the system chassis.
The peripheral bay holds up to four low-profile hot-plug disks and one removable media device (either
DVD or DAT).
Each Integrity rx7620-16 Server core I/O card set contains dual-channel Ultra160 SCSI controller
chips that support the SCSI devices in the internal peripheral bay. Each core I/O card set supports
two internal disks. It is important to note that separate controllers and SCSI buses manage the two
disks supported by the primary core I/O card set. A single controller and SCSI bus manage the
second pair of disks supported by the secondary core I/O card set. If use of more than two internal
disks is needed, the Integrity rx7620-16 Server will require both core I/O card sets.
Internal disks—The Integrity rx7620-16 Server holds up to four SCSI disks, which are accessible from
the front of the server. These are hot-plug disks, so they can be removed and inserted while the
Integrity rx7620-16 Server continues to operate. The system supports the following disks: 36 GB, 15K
rpm; 73 GB, 15K rpm; and 146 GB, 10K rpm.
Removable media—The Integrity rx7620-16 Server contains one removable-media bay, which
supports either a DVD drive or a DDS-4 DAT drive. Access to these devices is also from the front. The
DVD drive provides enhanced features while preserving backward read compatibility with CD-ROM
drives. Data transfer rates of up to 6.75 MB/s are achieved with the DVD format; 4.8 MB/s can be
achieved using the CD-R format. The DDS-4 drive has a maximum storage capacity of 40 GB, with a
peak transfer rate of 21.6 GB/hour (compressed).
HP Integrity rx8620-32 Server core I/O
The Integrity rx8620-32 Server chassis supports up to two core I/O cards, installed in core I/O slots
located along the right-rear vertical edge of the chassis. A minimum of one core I/O card must be
ordered with each system; the optional second core I/O card can be used to enable hardware
partitioning or to utilize the full capacity of the built-in mass storage bays.
