Scale-out Performance Storage Architecture

Kaminario SPEAR combines Dell™ PowerEdge™ blade servers, Kaminario K2 solid-state storage area network (SAN) and SPEAR Storage OS to create a fast, highly available and easy-to-deploy distributed storage grid appliance. SPEAR also supports Kaminario DataProtect™ storage services, which enables the K2 storage to provide end-to-end high availability and fast, high-volume data protection to solid-state drive (SSD) storage, while delivering extreme performance.

The Kaminario K2 SAN solid-state hardware is based on PowerEdge blade servers and comes with a rack and enclosure to hold the following hardware components:

Blade servers — for managing data and storing digital RAM (DRAM) and/or Flash SSDs for primary storage and hard disk drives (HDDs) or Flash SSDs for data backup and redundancy

Switches — for exposing Fibre Channel (FC) ports to multiple external hosts using FC switch, sending host data between blades using 10 Gigabit Ethernet (GbE) switch and supporting management communications between blades using one GbE switch Uninterrupted Power Supplies (UPS) — for delivering continuous power using two power supplies

SPEAR OS manages the following SPEAR components:

  • ioDirectors — load balances the data to optimize K2 system resources utilization and scalability
  • DataNodes — stores data in Flash or DRAM SSD and mirrors data for redundancy and data protection

SPEAR Storage OS has the following capabilities:

  • Automated Data Distribution™ — senses the capacity available in the I/O and storage tiers automatically to balance data distribution for consistent high performance and low latency
  • Intelligent Parallel I/O Processing™ — enables parallel I/O processing over multiple nodes to shorten the average response time of I/O requests
  • DataProtect™ — enables K2 to provide data protection to SSD storage while delivering extreme performance
