4 Assessment Overview FINANCIAL NEWS CUSTOMER has engaged Brocade Professional Services to perform a SAN Health Assessment Review of their Fabric Infrastructure. Due to the number of switches and fabrics this report has been broken into 8 separate reports that cover different fabrics. 4

5 Current Environment Overview Two Data Centers (PNJ & PNY) 12 Switches/Directors 11 Fabrics 1888 Ports with a 47% utilization 507 Attached Server HBA s 360 Storage/Tape HBA s 5

6 Brocade Fabric Switch and Director Overview Switches and Directors at Bloomberg port Port Directors 128 to 256 ports port 6

7 SAN Assessment Overview This SAN Assessment is based upon the SAN Health report file XXXXXXXX_071011_1540_All_US_XXXXXXX_SANs.BSH data captured on October 11, 2007 by. This Report is specific to the 11 Fabrics listed on the following slides. 7

11 SAN Assessment - Architecture Good practice is being followed or status is good: FINANCIAL NEWS CUSTOMER Deploys Dual Fabric SANs Hosts are dual attached Further review of the practice, observation, or status is recommended: Consolidation of equipment Oversubscription possible 11

12 SAN Assessment - Architecture Notes Port:ISL & Device: ISL ratios are high but since majority of traffic does not traverse ISL s this ratio is likely fine. If performance is lacking then consider adding more ISL s Items in highlighted in Orange are for your review. 12

14 SAN Assessment - Management Good practice is being followed or status is good: All devices are accessible from one location. Fabric Configuration Changes are performed one fabric at a time NTP is configured on most switches SNMP configured on most switches Fabric Watch is installed, licensed and enabled on most switches Further review of the practice, observation, or status is recommended: Update switches that need SNMP, NTP, FW. Implement fabric wide switch naming conventions 14

15 SAN Assessment - Operational Good practice is being followed or status is good: Actively maintains consistent & Up to Date Brocade FOS levels Failover is tested. To my knowledge FTP Trace is enabled and configured To my knowledge NTP is enabled and configured Switch configs are backed up (configuploads) Further review of the practice, observation, or status is recommended: NTP is setup but experiences failures due to management LAN FTP Trace is setup but experiences failures due to management LAN 15

16 SAN Assessment - Utilization Good practice is being followed or status is good: FINANCIAL NEWS CUSTOMER Fabrics are under 50% port utilization for most fabrics. Only 2 fabrics even exceed 50% utilization but are under 70% utilization. Currently there is adequate room for additional SAN attached devices and/or consolidation. There are no high port utilization concerns. Further review of the practice, observation, or status is recommended: No recommendations: Utilized resources are normal within the assessed environments. 16

18 SAN Assessment Device/Fabric Configurations Good practice is being followed or status is good: Symmetrical attachment of hosts Configuration settings are consistent across the environment. Telnet timeouts are consistent. Further review of the practice, observation, or status is recommended: Domain ID naming is confusing and overlapping. 18

19 SAN Assessment Device/Fabric Configurations The following table can be used RED = Not Recommended or not Best Practices. Can result in extended downtime or prompt notification. BLUE = Setting is inconsistent through fabric. Please review. 19

23 SAN Assessment - Zoning Good practice is being followed or status is good: Zoning actively implemented on all environments. Zone Database utilization is within recommended limits for all fabrics. Further review of the practice, observation, or status is recommended: Remove or Correct Hanging zones and Aliases Hanging Zone Member - A zone entry that has been defined in the zone configuration set, where one or more of its members are not physically connected to the fabric or not logged in during the time of SAN Health capture. Hanging Alias - An Alias entry that has been defined in the zone configuration set, where one or more of its members are not physically connected to the fabric or not logged in during the time of SAN Health capture. 23
