Azure HPC Cache Skill

This skill provides expert guidance for Azure HPC Cache. Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.

How to Use This Skill

IMPORTANT for Agent: Use the Category Index below to locate relevant sections. For categories with line ranges (e.g., L35-L120), use read_file with the specified lines. For categories with file links (e.g., [security.md](security.md)), use read_file on the linked reference file

IMPORTANT for Agent: If metadata.generated_at is more than 3 months old, suggest the user pull the latest version from the repository. If mcp_microsoftdocs tools are not available, suggest the user install it: Installation Guide

This skill requires network access to fetch documentation content:

Preferred: Use mcp_microsoftdocs:microsoft_docs_fetch with query string from=learn-agent-skill. Returns Markdown.
Fallback: Use fetch_webpage with query string from=learn-agent-skill&accept=text/markdown. Returns Markdown.

Category	Lines	Description
Troubleshooting	L37-L42	Diagnosing and resolving Azure HPC Cache issues with Blob storage firewalls and NFS storage targets, including connectivity, access, and configuration problems.
Best Practices	L43-L51	Guidance on optimizing Azure HPC Cache: client load balancing, efficient data movement and manual copy to Blob targets, NFS-on-Blob considerations, and priming caches for better hit rates.
Decision Making	L52-L57	Guidance on when Azure HPC Cache is appropriate, comparing usage models, workload patterns, performance needs, and deciding if/when to adopt it for your architecture.
Architecture & Design Patterns	L58-L63	Designing Azure HPC Cache namespaces across multiple back-end storage systems, and planning regional redundancy, high availability, and failover strategies for cached workloads.
Limits & Quotas	L64-L68	How to request and manage Azure HPC Cache quota increases, including limits on cache instances, capacities, and the support process for raising quotas.
Security	L69-L76	Configuring HPC Cache security: client access policies, directory/AD integration and extended groups, customer-managed encryption keys, and overall cache security settings.
Configuration	L77-L90	Configuring and operating Azure HPC Cache: CLI setup, networking/DNS/NTP, storage targets and namespaces, mounting NFS clients, lifecycle management, metrics, and environment prerequisites.
Integrations & Coding Patterns	L91-L98	Scripts and patterns for ingesting data (msrsync, parallelcp), controlling write-back with flush_file.py, and integrating Azure HPC Cache with Azure NetApp Files.
Deployment	L99-L103	Creating Azure HPC Cache instances via portal/CLI, and recreating or moving existing caches to a different region while preserving configuration and data paths

Install

Install with a command

npx skills add https://github.com/MicrosoftDocs/Agent-Skills --skill azure-hpc-cache

Paste it into your terminal and run it (requires Node.js). You can choose which agents to install it for, such as Claude Code or Codex.

Ask your agent

Please install the following Agent Skill.
https://github.com/MicrosoftDocs/Agent-Skills/tree/main/skills/azure-hpc-cache

First review SKILL.md and the bundled files and confirm there is nothing suspicious (such as sending data externally or reading credentials). Then place it in ~/.claude/skills/azure-hpc-cache/ for Claude Code, or ~/.agents/skills/azure-hpc-cache/ for Codex.

Send this text to Claude Code or Codex as is. It checks the contents before installing.
