Figure 51 Graph showing times when host l82ar155 accessed the Symmetrix array
The two peak times when host l82ar155 accessed the Symmetrix array are
identical to the times when host l82ar156 accessed the Symmetrix array (9 A.M.
and 6 P.M.). Because host l82ar155 was accessing the devices that share the
same disk spindle on the Symmetrix array as host 182ar156, the competing
workload caused the performance degradation.
