  40. 40. 40© Copyright 2014 EMC Corporation. All rights reserved.© Copyright 2014 EMC Corporation. All rights reserved. Hot topics - Connectrix-B (Brocade) • Problem: Stuck Virtual Channel (VC) • Symptom: – Performance issues – Switch Log contains: • 2011/11/21-15:37:01:534223, [C2-5021], 115166/0, SLOT 6 " CHASSIS, WARNING, ED_48000B, S10,P-1(5): Link Timeout… • Solution: – See Brocade DEFECT000342738 • Only an issue with 8G Brocade switches • Fixed at >= 6.4.2a – Contact support for procedure (if upgrading) • 8G 64 Port line card seems to be particularly susceptible
  41. 41. 41© Copyright 2014 EMC Corporation. All rights reserved.© Copyright 2014 EMC Corporation. All rights reserved. Hot topics - Connectrix-B (Brocade) • Problem: Webtools/Java compatibility • Symptom: Webtools fails to launch after Java is upgraded to version 7 update 40 or higher • Solution(s): – downgrade Java to Java 7u25 or earlier – Modify java.security configuration file • See EMC 000177076 for more information • Prevention: – Refer to release notes for supported versions
  42. 42. 42© Copyright 2014 EMC Corporation. All rights reserved.© Copyright 2014 EMC Corporation. All rights reserved. Hot topics - Connectrix-B (Brocade) • Problem: FCIP stability • Symptom: FCIP tunnels bouncing or stuck at In- Progress • Solution(s): – Brocade is recommending that all environments using FCIP upgrade to 7.1.0c and above.
  43. 43. 43© Copyright 2014 EMC Corporation. All rights reserved.© Copyright 2014 EMC Corporation. All rights reserved. Hot topics - Connectrix-C (Cisco) • Problem: FCoE performance • Symptom(s): – Poor I/O performance is observed. – FCOE attached hosts (using CNAs) log abort errors – The FCOE interfaces on the Nexus switch where the FEX (Nexus 2000 series) module attaches will log increasing pause frames • From the SAN towards the CNA on the FEX. – Storage attached interfaces on the MDS switch log high buffer transitions to zero • Solution: – Configure Jumbo frames on lossless priority – Upgrade to NX-OS 5.1(3)N1(1a) or above (see CSCtz63490)
  44. 44. 44© Copyright 2014 EMC Corporation. All rights reserved.© Copyright 2014 EMC Corporation. All rights reserved. Hot topics - Connectrix-C (Cisco) • Problem: DCNM login display issue • Symptom: Web GUI does not display the NPV host device under inventory • Solution: None – See CSCui69324
  45. 45. 45© Copyright 2014 EMC Corporation. All rights reserved.© Copyright 2014 EMC Corporation. All rights reserved. Hot topics - Connectrix-C (Cisco) • Problem: GUI performance • Symptom: – General performance issues, slowness, – The web gui will occasionally log an error that tells you specifically to vacuum the database to improve performance • Solution: – EMC 000176676 - Cisco: How to vacuum Postgres Database for Windows based DCNM Installs
  46. 46. 46© Copyright 2014 EMC Corporation. All rights reserved.© Copyright 2014 EMC Corporation. All rights reserved. Hot topics – Distance Extension • Best practices – For all client-side ports (i.e. E_ports) attached to distance devices: • Hard-set the port-speed to the highest expected link rate (i.e. remove auto-negotiation). This will reduce the link initialization time after unexpected link-bounces – For switches that support BBScN, use it. • There are times when credits/R_RDYs are lost and this feature is used to recover them. • For Brocade switches this is under the “Brocade Credit Recovery” feature. • For Cisco switches, there’s a BBScN feature/mode.
  47. 47. 47© Copyright 2014 EMC Corporation. All rights reserved.© Copyright 2014 EMC Corporation. All rights reserved. Hot topics – Distance Extension • Best practices – Verify optimum optical medium conditions: • Verify clean Fiber Optic cables • No mismatching of different Fiber Optic cable core sizes • Verify light levels are within thresholds
  48. 48. 48© Copyright 2014 EMC Corporation. All rights reserved.© Copyright 2014 EMC Corporation. All rights reserved. Hot topics – Remote Replication • Problem: Degraded SRDF Performance • Symptom(s): – Poor I/O performance is observed. – High BBC=0 on RF or ISL ports • Contributing factors – SAN switch ISLs extended over DWDM or Wan extender – ISLs throttled to 1-2Gb for extender connectivity • Solution: – Add additional ISLs to compensate for reduced speeds – Verify no oversubscription on ISL and RF ports on switches – Verify extender configuration: speed limits, compression, etc – Verify RFs spread evenly across all Fabrics/Wan paths
  49. 49. 49© Copyright 2014 EMC Corporation. All rights reserved.© Copyright 2014 EMC Corporation. All rights reserved. Hot topics – Remote Replication • Problem: Degraded Performance • Symptom(s): – Poor I/O performance or response time is observed. – Logging link errors • Solution: – Guaranteed bandwidth (use network qos for shared networks) – Verify speed limits to match guaranteed bandwidth – Verify host workload has not out-paced replication links – may need to add more links – For synchronous replication, enough RA links to maintain <40% utilization
