LUN performance

Hi All,

For two LUN in my environment I see status: misaligned. Hosts (VMs) use Windows 2003 system.

                Multiprotocol type: vmware

                Alignment: misaligned

                Write alignment histogram percentage: 8, 0, 0, 15, 19, 23, 8, 1

                Read alignment histogram percentage: 21, 1, 1, 7, 28, 6, 2, 1

                Partial writes percentage: 21

                Partial reads percentage: 28

                Multiprotocol type: vmware

                Alignment: misaligned

                Write alignment histogram percentage: 40, 0, 0, 33, 6, 0, 0, 0

                Read alignment histogram percentage: 50, 0, 0, 46, 2, 0, 0, 0

                Partial writes percentage: 19

                Partial reads percentage: 0

Have this impact our performance? how to resolve this problem.

Best regards, KOSA
