32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- HPE Primera
- Mission-critical all-flash array with 100% availability guarantee, NVMe architecture, and AI-driven InfoSight analytics for predictive operations.
- HPE Nimble Storage
- Midrange adaptive flash storage platform with scale-out architecture, predictive analytics, and integrated backup and replication.
- HPE MSA
- Entry-level storage array offering affordable SAN/DAS connectivity, simple management, and high availability for SMBs.
- HPE StoreOnce
- Deduplication backup appliance family supporting Catalyst and RMC protocols, with cloud integration for long-term retention.
- HPE SimpliVity
- Hyperconverged infrastructure solution combining compute, storage, and backup with built-in deduplication and compression.
- RAID 5 usable capacity
- Usable capacity equals (number of drives minus one) times single drive capacity, because one drive's worth of space is used for parity.
- RAID 6 usable capacity
- Usable capacity equals (number of drives minus two) times single drive capacity, due to dual parity for double fault tolerance.
- NVMe over Fabrics
- Protocol extension that enables NVMe commands to traverse network fabrics like RDMA or Fibre Channel, reducing latency and CPU overhead.
- Thin provisioning
- Allocation method that assigns storage capacity on demand rather than upfront, improving utilization but requiring monitoring to prevent overcommit.
- Synchronous replication
- Data replication method where writes are acknowledged only after being committed to both primary and secondary sites, ensuring zero RPO but requiring low latency.
- Erasure coding
- Data protection technique that divides data into fragments, encodes with redundancy, and distributes across nodes for higher capacity efficiency than mirroring.
- IOPS estimation formula
- Total IOPS equals number of drives multiplied by IOPS per drive, adjusted for RAID write penalty (e.g., RAID 5 penalty of 4).
- Storage capacity planning
- Calculate usable capacity by subtracting parity and spare overhead from raw capacity, then add 20-30% headroom for growth.
- RPO and RTO
- Recovery Point Objective defines maximum acceptable data loss; Recovery Time Objective defines maximum acceptable downtime after a disruption.
- Multipath I/O design
- Designing redundant paths from host to storage using dual fabrics or NICs to prevent single points of failure and enable load balancing.
- HPE Smart SAN
- HPE tool that automates Fibre Channel zoning for HPE storage arrays, reducing configuration errors and simplifying SAN deployment.
- Single-initiator-single-target zoning
- FC zoning best practice that creates one zone per host HBA and storage port pair, improving security and troubleshooting.
- CPG in HPE Primera
- Common Provisioning Group is a virtual pool of storage from which volumes are created, enabling thin provisioning and wide striping.
- Host Explorer
- HPE tool that collects host configuration data for support and validation, helping ensure proper multipath and HBA settings.
- HPE InfoSight
- Cloud-based AI analytics platform that provides predictive support, cross-stack insights, and recommendations for HPE storage and servers.
- SSMC
- StoreServ Management Console is the management interface for HPE Primera and 3PAR arrays, used for configuration, monitoring, and reporting.
- Peer Persistence
- HPE Primera/3PAR feature that enables transparent failover of hosts between arrays using synchronous replication and automatic path switching.
- StoreOnce Catalyst
- HPE backup protocol that provides deduplicated backup and replication, with support for Fibre Channel and Ethernet, and cloud tiering.
- Immutable snapshots
- Snapshots that cannot be altered or deleted for a set period, protecting data from ransomware and accidental modification.
- Performance bottleneck isolation
- Process of using array and host metrics (IOPS, latency, queue depth) to identify whether storage, network, or host is limiting performance.
- RAID write penalty
- Extra I/O operations required for parity RAID writes: RAID 5 penalty is 4 (read-modify-write), RAID 6 is 6.
- Wide striping
- HPE Primera/3PAR technique that spreads volumes across all drives in a CPG, balancing load and improving performance.
- iSCSI jumbo frames
- Ethernet frames larger than 1500 bytes (typically 9000) that can improve iSCSI throughput but must be configured end-to-end.
- VAAI integration
- vSphere APIs for Array Integration offload storage operations like cloning and zeroing to HPE arrays, improving performance and efficiency.
- HPE Cloud Volumes
- Cloud-native block storage service for AWS and Azure, managed by HPE, used for dev/test, DR, and cloud bursting.
- HPE Apollo
- High-performance compute and storage platform designed for AI, analytics, and unstructured data workloads requiring scale-out throughput.
- SMB SAN scenario
- Small business needing affordable, simple SAN with high availability typically selects HPE MSA for entry-level block storage.
