SanDisk ION Accelerator Data Sheet

The SanDisk ION Accelerator delivers game-changing performance for database applications. Consisting of SanDisk ION Accelerator software and Fusion ioMemory PCIe cards, it provides shared all-flash storage, which is highly available and performance optimized for use with a choice of capacity and SAN connectivity options, including 16Gb Fibre Channel, 56Gb InfiniBand and 40Gb iSCSI.


SanDisk ION Accelerator Performance Architecture

Developed from the ground up for performance, SanDisk ION Accelerator’s design incorporates a streamlined, innovative SanDisk ION Accelerator 2.5.0 software stack that eliminates bottlenecks, taking advantage of our low latency Fusion ioMemory products.

  • Enables server-side Fusion ioMemory to be shared storage for database acceleration
  • Delivers a high performing 1.9 million sequential IOPS1, 25GB/s sequential bandwidth2 and 85 microsecond low latency for random workload acceleration.3, 4
  • Efficient density with incremental scalable storage of up to 51.2TB Fusion (ioMemory capacity in 1U – 4U of space (based on a compatible server
  • Multi-lane PCIe architecture scales performance with capacity and reduces bottlenecks from slower storage protocol interfaces used by other systems
  • Durability with proven Fusion ioMemory data protection technology such as Adaptive Flashback
  • Deployment in standalone or High-Availability mode. With High-Availability, SanDisk ION Accelerator simultaneously accelerates performance for volumes distributed across two system.


Database Acceleration

The SanDisk ION Accelerator enables top database applications to run at the highest levels of performance. For application environments ranging from OLTP (Microsoft SQL Server, Oracle RAC) to OLAP (SAP HANA), the SanDisk ION Accelerator delivers exceptional acceleration. And, it seamlessly integrates with Oracle Enterprise Manager to deliver simple capacity planning and historical performance monitoring.

SanDisk conducted a synthetic performance test4 on Supermicro SYS-6037R-TXRF with 128GB RAM. Eight Fusion ioMemory SX300-3200 PCIe cards were configured in direct access mode. For high availability mode two Supermicros and 16 PCIEe cards were used. The performance test was conducted using SanDisk ION Accelerator software version 2.5.0, using an InfiniBand fabric and eight initiators. The fio benchmark program was used to generate the workload and to measure performance. The SanDisk ION Accelerator solution was able to achieve up to 1.9 million IOPS for sequential workloads.
