Live Migrate and Volume Advisor
SC Series Federation Live Migrate go beyond ` SC platform lets you harness the combined capacity and performance of multiple arrays Abstract/separate data from hardware 6PB 6PB 1PB 1PB 3PB 5PB 4PB 3PB LUN Transparent volume mobility Move volumes/workloads between arrays with ZERO downtime, no impact to snapshots or replication protection Intuitive, unified management, global reporting and alerts Heterogeneous federations (SC9000, SC8000, SC7020, SC5020, SC4020) Volume Advisor monitors federated arrays, suggests best data placement Balance workloads on demand 5
Live Migrate: Multi-array federation Manage storage at the data center level LUN Data movement within federation does NOT affect workloads Federated cluster Rebalance your data center arrays in minutes! 1. Volume Advisor sends alert 2. Start Live Migrate wizard, accept recommendations 3. Click complete migration Standard SC Series feature* 6 Volume Advisor Monitors federated storage cluster Recommends ideal load balancing Live Migrate Move volumes anywhere within the federated storage cluster 100% storage-side control no need to involve server/app teams Offer a consistent, highly-available storage service for your business * Available on SC9000, SC8000, SC7020, SC5020, and SC4020 arrays. Federation may include like or unlike models.

Recorded Lab Demo Volume Advisor Live Migrate
Volume Advisor Use Cases Two key things to remember: All uses cases are proactive in nature All use cases maintain zero application down time All use cases are threshold based to: Adhere to predefined SLAs with customers (ie. IOPS, throughput, latency) Provide storage resource balancing Resolve noisy neighbor conflicts 18
Live Migrate Use Cases Two key things to remember: All uses cases are proactive in nature All use cases maintain zero application down time Use Live Migrate for: Adhering to predefined SLAs with customers (ie. IOPS, throughput, latency) Providing storage resource balancing Resolving noisy neighbor conflicts Planned maintenance Scale out storage performance/capacity growth Disaster avoidance 19
