You’ve surely invested a great deal of time and money in your INFINIDAT 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 InfiniBox storage array configuration. Unfortunately, even a minor gap between storage, compute and networking can put an entire business application at risk.
INFINIDAT 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 automatically detects InfiniBox storage arrays and their configuration, including:
- Model, revision, capacity, etc.
- InfiniBox nodes, Front-end directors and Fibre-channel ports
- InfiniBox NAS and file system
- InfiniBox storage pool and InfiniBox volume configuration
- LUN mapping and masking configuration
- Replication and Point in Time copies (dependencies, state, etc.) – Remote Copy, Snapshot, Clone
- InfiniBox Consistency groups
INFINIDAT Configuration Vulnerabilities
AvailabilityGuard performs InfiniBox risk analysis and checks for configuration issues or best-practice violations. Here are a few examples:
- Host access to InfiniBox volumes – single point of failure detection
- Cluster data access risks (e.g., standby does not see all shared volumes, has reduced bandwidth, etc.)
- Detect data access risks (e.g., dead paths, sub-optimal multi-pathing policies, potential tampering, and more)
- Detect storage alignment issues (e.g., database files, VMware VMFS, etc.)
- Incorrect masking configuration
- Identify cross-array configuration errors (e.g., LVM objects striped across multiple arrays; mirrored LVs kept on a single array, inappropriate consistency configuration and more)
- Incorrect VMware SRM protection group configuration for InfiniBox
InfiniBox Replication Considerations
AvailabilityGuard provides deep analysis of replication and mirroring, including InfiniBox Remote Copy, Clone and Snapshot. A few key checks are listed below – see more info on appropriate solution pages.
- Detect partial replication
- Detect potentially inconsistent replication
- Incorrect or incomplete consistency group definition
- Detect RPO and retention violations
- Incorrect alignment to replicated storage (e.g., database data and log on same volume)
- Detect redundant / old replicas
