HP StoreOnce 6500 Backup Installation Planning and Preparation Guide

Physical Ethernet connection requirements
Be aware of the following when preparing the network environment.
• All network subnets must use bonded ports to ensure high availability in the event of failover.
Incorrect cabling can negate the high availability infrastructure of the product.
• There should ideally be two switches for each network to which you are connecting.
• For EACH bonded pair of cables, the first cable should be connected to Switch 1; the other
cable should be connected to Switch 2. Note that for Mode 4 (LACP) bonding this is only
possible if the two switches are joined via an Inter Switch Link.
• If using separate subnets for data and management and multiple external switches are used,
these switches must support a Multi Chassis Link Aggregation protocol that is compatible with
the rest of the customer’s network switch infrastructure. For more information, see the white
paper at http://h20195.www2.hp.com/v2/GetPDF.aspx/4AA3-4841ENW.pdf.
• When using a 10GbE network, SFPs are required. These are supplied with the product, two
for each node in a couplet.
• The 1GbE ports have an RJ45 connection type; CAT6 is recommended, CAT5E is the minimum
requirement.
Portsets
Network ports are bonded to enable resilience and support failover. This configuration of physical
ports and network bonding mode is called a portset. The portset is defined first and a subnet is
then configured to use that portset. At initial configuration there are twelve permutations for a
portset, as shown below. The first eleven options are the various combinations for the four 1GbE
ports for bonding; there is only one possible combination for the two 10GbE ports.
Select bond configuration :
1 = eth0, eth1 (1 Gig) (default)
2 = eth0, eth2 (1 Gig)
3 = eth1, eth2 (1 Gig)
4 = eth0, eth1, eth2 (1 Gig)
5 = eth0, eth3 (1 Gig)
6 = eth1, eth3 (1 Gig)
7 = eth0, eth1, eth3 (1 Gig)
8 = eth2, eth3 (1 Gig)
9 = eth0, eth2, eth3 (1 Gig)
10 = eth1, eth2, eth3 (1 Gig)
11 = eth0, eth1, eth2, eth3 (1 Gig)
12 = eth5, eth7 (10 Gig)
