Validate ConfigurationON EMC VPLEX

You’ve surely invested a great deal of time and money in your EMC VPLEX environment and carefully designed and implemented redundancy, availability and data protection. But what guarantees that your storage service will always deliver the required level of availability and efficiency that you expect?

It is difficult to maintain a configuration that is always aligned with vendor best-practices, and even harder to ensure that changes in other IT layers are well aligned with your EMC VPLEX configuration. Unfortunately, even a minor gap between storage, compute and networking can put an entire business application at risk.

EMC VPLEX Configuration Analysis

A well-designed foundation is where it all starts or ends as the slightest misconfiguration can affect hundreds of servers and cause service or data loss issues. AvailabilityGuard makes sure that your EMC VPLEX environment is configured according to best-practices, and free of data loss and downtime risks.

AvailabilityGuard analyzes the configuration of all the different EMC VPLEX modes, including VPLEX Local, VPLEX Metro, and VPLEX Geo. AvailabilityGuard detects a large number of VPLEX misconfigurations, including both internal VPLEX issues, as well as issues that span the VPLEX configuration and other IT layers. VPLEX configuration issues detected include:

  • VPLEX SAN I/O best practices (number of paths, use of PowerPath/VE, Path selection Policy, etc.)
  • VPLEX guidelines for the configuration of System Volumes, Port Groups and more.
  • VPLEX Consistency Groups (CG) best practices (auto resume setting, automatic winner setting and more)
  • Correct configuration of VPLEX Witness

Aligning VPLEX and Storage Configuration

Proper alignment of the storage layer with your VPLEX configuration is vital. If key best practices are not met, serious data and performance risks could arise. AvailabilityGuard protects you from configuration issues relative to those underlying physical storage devices that your VPLEX is connected to.

This allows you to detect single-points-of-failure and misconfiguration with EMC VNX, EMC VMAX, NetApp, etc.

  • Detect single-points-of-failure on the I/O path from the VPLEX system to the managed storage arrays, and through the SAN switches
  • Correct configuration of Consistency Groups at the VPLEX level, underlying storage array level and RecoverPoint.
  • Unauthorized access to storage LUNs used by VPLEX
  • Ensure point-in-time copies are complete and consistent (clone, snapshots, etc.)

Detecting Issues between VPLEX and Hosts

AvailabilityGuard checks that your host configuration is aligned both with EMC VPLEX and your Linux, Windows or Solaris hosts. AvailabilityGuard check for the following host misconfigurations:

  • Consistent VPLEX virtual volume configuration for file systems and databases (RAID level, thin provisioning, device type/tier and more)
  • Detach rule-set include all required devices
  • Detect single-points-of-failure on the I/O path from the host to VPLEX, and through the SAN switches
  • Detect VPLEX RPO SLA violation
  • Host clustering best practices for a VPLEX environment (Oracle RAC, Microsoft Cluster, PowerHA, etc.)
  • Unix virtualization best practices for a VPLEX environment (PowerVM)

VPLEX and VMware (ESXi)

  • vSphere Metro Storage Cluster (vMSC) best practices
  • VMware DRS, FT, Heartbeat datastores, Admission control guidelines and more
  • Correct PowerPath/VE or NMP I/O path configuration in cross connect environment
