StorMagic SvSAN 6.1 Product Announcement Webinar and Live Demonstration Mark Christie – Senior Systems Engineer
Introducing StorMagic What do we do? StorMagic SvSAN eliminates the need for physical SANs by exposing the storage of an industry standard server as a virtual SAN thereby dramatically reducing CAPEX and OPEX. How does SvSAN achieve this? StorMagic’s virtual SAN converts the internal disk, flash and memory of industry standard servers into robust, cost effective and flexible shared-storage. Where is this most applicable? SvSAN is deployed for hyperconverged infrastructure for multi-site enterprises and SMEs and server- based storage arrays as an alternative to a traditional physical SAN.
Introducing StorMagic Across Many Global Customer 1 to Thousands Global Partner Adoption Verticals of Sites Network Large and small deployments Wherever you are, StorMagic has Retail, health, government, Within 72 countries, organisations from enterprises with 1000s of resellers, integrators, and server industrial, education, finance, depend on StorMagic for sever sites to SMEs with a single site partners to meet your needs pharma and many more and storage infrastructure
What is a Storage Array? Wikipedia Definition: A disk array is a hardware element that contains a large group of hard disk drives (HDDs). It may contain several disk drive trays and has an architecture which improves speed and increases data protection. The system is run via a storage controller, which coordinates activity within the unit.

SvSAN – SSD Caching SSD Read/Write Caching • Data acknowledged once written to Flash storage enabling for high random IO performance • Sequentially written back to magnetics at a later time to minimize disk head movements Hot Blocks • Clean flushed data persists until space is required enabling read performance increase Increase Performance and Efficiency • IO tracked to promote into cache tiers over time • Less workload on spinning disks enables greater efficiency Sizing and Configuration • Single SSD or hardware and software RAID for protection • Recommended cache capacity 10% of pool storage Example - 200GB cache, 2TB pool storage. •
SvSAN 6: Memory based caching Read-ahead mode Modern servers now have vast amounts of memory • Detects sequential read streams to allow read ahead • Additional memory can be used to dramatically improve • i.e. when this block is read it is highly likely adjacent storage performance blocks will be read • Frequently read data is cached in memory • Enable for targeted workloads • Read operations are served from memory without ever accessing a disk drive Most frequently used mode (default) • SvSAN algorithm identifies and stores data based on access patterns Data pinning mode • Frequently accessed data blocks are stored in memory • Enter learning to create identical access pattern • Default mode benefits all workloads • Delivers most efficient read performance • Enable for targeted workloads
SvSAN - Predictive automated read caching & tiering Intelligent read caching algorithm • All read I/Os are monitored and analyzed • Most frequently used data – “Hot” data • Cache tiers are populated based on access frequency Tiering • RAM: Most frequently accessed data • SSD/Flash: Next most frequently accessed data • HDD: Infrequently accessed data – “Cold” data Sizing • Assign cache sizes to meet requirements • Grow caches as working sets change • Use any combination of Memory, SSD/Flash and Disk Play to the strengths • Play to the strengths of all mediums • Memory Highest IOPS • SSD/Flash Magnetic drives providing lower price per GB
