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.

What is a Storage Array?

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. Wikipedia Definition:

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

Modern servers now have vast amounts of memory

  • Additional memory can be used to dramatically improve

storage performance

  • Frequently read data is cached in memory
  • Read operations are served from memory without ever

accessing a disk drive Read-ahead mode

  • Detects sequential read streams to allow read ahead
  • i.e. when this block is read it is highly likely adjacent

blocks will be read

  • Enable for targeted workloads

Most frequently used mode (default)

  • SvSAN algorithm identifies and stores data based on

access patterns

  • Frequently accessed data blocks are stored in memory
  • Default mode benefits all workloads

Data pinning mode

  • Enter learning to create identical access pattern
  • Delivers most efficient read performance
  • Enable for targeted workloads
slide-19
SLIDE 19

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

Estimates

  • SSD & memory: 94% of I/O being satisfied from read cache, when using 2GB

memory and 120GB SSD

  • Memory only: 94% of I/O being satisfied from read cache when using 2GB of

memory Testing

  • Replay the exact workload collected from live environment
  • No best guess synthetic workload but exact patterns from data collection

Conclusion

  • Environment sufficient for workloads
  • Allocate a small amount of memory to satisfy almost all reads

SvSAN 6.1 Predictive Cached Tiering Deployment Examples

  • I am selecting a new server and storage solution

̶ Consider 3 tier architecture or hyperconverged and the best balance of storage tiers for capacity and performance ̶ Solution 1: Hyperconverged with tiering across HDD, SSD and Memory. ̶ Solution 2: Server-based storage array with tiering across HDD, SSD and Memory and separate compute

  • I am considering an all flash array

̶ Know your actual IOps requirement and decide how important low latency is ̶ Solution 1: Memory caching with HDDs for lower capacity and lowest cost ̶ Solution 2: Memory and SSD caching with HDDs for higher capacity and balanced cost ̶ Solution 3: Memory caching with a full Flash array for highest performance and highest cost

  • I am an existing SvSAN user with only HDD

̶ Minimal invasive upgrade for maximum ROI ̶ Solution 1: Leverage spare memory for Memory caching ̶ Solution 2: Upgrade memory for Memory caching

  • I am an existing SvSAN user with SSD caching or all Flash

̶ Increase IOps and reduce latency with SSD and memory read/write caching ̶ Solution 1: Add SSD read caching. ̶ Solution 2: Add SSD and Memory read caching through spare memory or a minor upgrade
