(46 inch) aisle width between the rows. Although this may be a larger aisle than you have used
before, your Parallel Sysplex will benefit from the improvement in cooling that a wider aisle provides.
(See Figure 10 on page 43.)
Note: Figure 10 on page 43 shows a minimum aisle width of 941 mm (37 in). Although this width is
adequate for a congested computer room floor, it is the minimum you should use. An aisle 1168 mm
(46 inch) wide will better serve the cooling and cabling needs of a Parallel Sysplex configuration.

3. Sysplex connections can be made using ISC-3 and InfiniBand fiber optic link cabling. The Sysplex
itself may be comprised of servers connected to a Sysplex Timer, servers connected to each other
through the Server Time Protocol feature (STP), or a mixture of both types of connections.
Notes:
a. zEC12 has no External Time Reference (ETR) capability.
b. z9 EC, z9 BC, z990, z890, z900, and z800 cannot participate in a Parallel Sysplex with zEC12.
zEC12 can only communicate directly with zEC12, zBC12, z196, z114, z10 EC, and z10 BC.
4. As the Parallel Sysplex grows, add new servers evenly on either side of the central coupling facilities.
