12 Best Practices for Deploying a Mixed 1Gb/10Gb Ethernet SAN using Dell Storage PS Series Arrays | BP1008
 B: One PowerEdge server with two 1Gb SAN ports connecting to four volumes in one PS Series
10Gb array via stacked Dell Networking N3000 Series switches and LAGd Dell Networking N4000
Series switches
 C: One PowerEdge server with two 1Gb SAN ports connecting simultaneously to separate speed
pools: two volumes in one PS Series 1Gb array and two volumes in one PS Series 10Gb array.
 D: One PowerEdge server with two 1Gb SAN ports connecting simultaneously to four volumes stored
in a mixed speed pool consisting of one PS Series 1Gb array and one PS Series 10Gb array.
Parts A and B provide I/O performance data for comparing the difference when connecting 1Gb initiators to
1Gb vs. 10Gb arrays.
Parts C and D provide I/O performance data for comparing I/O performance when a 1Gb initiator
simultaneously connects to volumes in separate speed pools vs. connecting to the same set of volumes in a
single mixed speed pool.
Figure 7 illustrates the I/O flow paths for the 1Gb host initiator accessing 1Gb storage targets or 10Gb storage
targets. Figure 8 shows the comparison of performance between 1Gb storage and 10Gb storage targets
where the 1Gb storage target is the baseline.
