This section outlines the best practices for configuring the network in the Ready Solution for SQL Server.
Best practices for configuring the LAN include:
- Use two 10 GbE S4048-ON network switches for end-to-end client traffic to prevent a single point of failure.
- Use VLAN tagging to sustain switch failure, and use NIC teaming to provide multitier network high availability.
- Use NIC teaming to provide high availability at the NIC port level.
- Use NIC teaming for virtual and physical network connections.
- Use a minimum of two network cards to provide high availability and prevent a single point of failure.
- Use two Intel Ethernet 10 GbE dual-port X710 adapter cards to enable connectivity between the SQL Server host and applications on the external network.
Best practices for designing the SAN include:
- Use redundant Connectrix 6610 switches to prevent a single point of failure.
- Use two Emulex LightPulse LPE31002 cards per server for high availability.
- Use named zoning of end devices (FC HBAs) and Dell EMC Storage Center virtual ports while creating zones. Named zoning provides better flexibility because it does not bind the devices and virtual ports to specific physical ports on either the switch or the storage array.
- Make crisscross cable connections between redundant FC HBA cards and redundant FC switches to enable high availability, as shown in the following figure.
