6 cables (up to

55 meters) or Cat 6a cables (up to

100 meters) can also be used. The 10GBase-T ports on the database servers can be bonded together using host-based bonding. There is no need for extra transceivers or cables, which reduces the TCO significantly. For uplink connectivity, one or more QSFP+ ports from each of the Oracle Ethernet Switch ES2-64 switches are connected to upstream switches. If the upstream switch supports QSFP+

40 GbE connectivity, the QSFP+ port on Oracle Ethernet Switch ES2-64 can be plugged to the QSFP+ port on the upstream switch using either copper or optical cabling. However, if the upstream switch supports only

10 GbE ports, the QSFP+ ports on the switch should be connected using splitter cables. Oracle has both copper and optical splitter cables in various lengths (see Table 1). Figure

2 shows the connectivity for the eighth-rack configuration of Exadata Database Machine X5.
