58 EqualLogic Configuration Guide | Version 15.2 | August 2014
 When connecting 1Gb switches and 10Gb switches together you must always be aware of where
Rapid Spanning Tree is going to block links to make sure that 10Gb traffic (i.e. EqualLogic inter-array
data flow) never crosses the 1Gb switch.
 You must configure pools and volumes in a way that minimizes impact to IO performance.
- Where possible, always connect 1Gb hosts only to 1Gb arrays and 10Gb hosts only to 10Gb
arrays (except when performing migration tasks). Intermixing speeds may cause
oversubscription of ports and lead to high latency or high retransmits.
- When adding 10Gb arrays, place them in separate pools from your 1Gb arrays.
