<h1 id="global-cache-pooling">Global Cache Pooling</h1>
<p>This document describes how to use MooncakeStore as the KV Cache storage backend for FastDeploy, enabling <strong>Global Cache Pooling</strong> across multiple inference instances.</p>
<h2 id="overview">Overview</h2>
<h3 id="what-is-global-cache-pooling">What is Global Cache Pooling?</h3>
<p>Global Cache Pooling allows multiple FastDeploy instances to share KV Cache through a distributed storage layer. This enables:</p>
<ul>
<li><strong>Cross-instance cache reuse</strong>: KV Cache computed by one instance can be reused by another</li>
<li><strong>PD Disaggregation optimization</strong>: Prefill and Decode instances can share cache seamlessly</li>
<li><strong>Reduced computation</strong>: Avoid redundant prefix computation across requests</li>
</ul>

<h3 id="scenario-1-multi-instance-cache-sharing">Scenario 1: Multi-Instance Cache Sharing</h3>
<p>Run multiple FastDeploy instances sharing a global KV Cache pool.</p>
<p><strong>Step 1: Start Mooncake Master</strong></p>
<pre><code class="language-bash">mooncake_master \
--port=15001 \
--enable_http_metadata_server=true \
--http_metadata_server_host=0.0.0.0 \

--metrics_port=15003
</code></pre>
<p><strong>Step 2: Start FastDeploy Instances</strong></p>
<p>Instance 0:</p>
<pre><code class="language-bash">export MOONCAKE_CONFIG_PATH=&quot;./mooncake_config.json&quot;
export CUDA_VISIBLE_DEVICES=0
python -m fastdeploy.entrypoints.openai.api_server \
--model ${MODEL_NAME} \
--port 52700 \
--max-model-len 32768 \
--max-num-seqs 32 \
--kvcache-storage-backend mooncake
</code></pre>
<p>Instance 1:</p>
<pre><code class="language-bash">export MOONCAKE_CONFIG_PATH=&quot;./mooncake_config.json&quot;

--max-num-seqs 32 \
--kvcache-storage-backend mooncake
</code></pre>
<p><strong>Step 3: Test Cache Reuse</strong></p>
<p>Send the same prompt to both instances. The second instance should reuse the KV Cache computed by the first instance.</p>
<pre><code class="language-bash"># Request to Instance 0
curl -X POST &quot;http://0.0.0.0:52700/v1/chat/completions&quot; \

# Request to Instance 1 (should hit cached KV)
curl -X POST &quot;http://0.0.0.0:52800/v1/chat/completions&quot; \
-H &quot;Content-Type: application/json&quot; \

<h2 id="verification">Verification</h2>
<h3 id="check-cache-hit">Check Cache Hit</h3>
<p>To verify cache hit in logs:</p>
<pre><code class="language-bash"># For multi-instance scenario
grep -E &quot;storage_cache_token_num&quot; log_*/api_server.log
# For PD disaggregation scenario
grep -E &quot;storage_cache_token_num&quot; log_prefill/api_server.log
</code></pre>
<p>If <code>storage_cache_token_num &gt; 0</code>, the instance successfully read cached KV blocks from the global pool.</p>
<h3 id="monitor-mooncake-master">Monitor Mooncake Master</h3>
<pre><code class="language-bash"># Check master status
curl http://localhost:15002/metadata
# Check metrics (if metrics_port is configured)
curl http://localhost:15003/metrics
</code></pre>
<h2 id="troubleshooting">Troubleshooting</h2>
<h3 id="common-issues">Common Issues</h3>
<p><strong>1. Port Already in Use</strong></p>
<pre><code class="language-bash"># Check port usage
ss -ltn | grep 15001
# Kill existing process
kill -9 $(lsof -t -i:15001)
</code></pre>
<p><strong>2. RDMA Connection Failed</strong></p>
<ul>
<li>Verify RDMA devices: <code>ibv_devices</code></li>
<li>Check RDMA network: <code>ibv_devinfo</code></li>
<li>Fallback to TCP: Set <code>MOONCAKE_PROTOCOL=tcp</code></li>
</ul>
<p><strong>3. Cache Not Being Shared</strong></p>
<ul>
<li>Verify all instances connect to the same Mooncake master</li>
<li>Check metadata server URL is consistent</li>
<li>Verify <code>global_segment_size</code> is large enough</li>
</ul>
<p><strong>4. Permission Denied on /dev/shm</strong></p>
<pre><code class="language-bash"># Clean up stale shared memory files
find /dev/shm -type f -print0 | xargs -0 rm -f
</code></pre>
<h3 id="debug-mode">Debug Mode</h3>
<p>Enable debug logging:</p>
<pre><code class="language-bash">export FD_DEBUG=1
