Drivers for High-Performance Storage

FLASH USE CASES SUPPORTS APPLICATIONS THAT REQUIRE RANDOM WORKLOADS File Shares (unstructured) SQL Server Database Analytics Apps (Unix/Linux) VMware/VDI environments Oracle Database (Red Hat/OVM) File System NFS/CIFS CSV/NTFS GPFS/GFS HDFS/JFFS VMFS OCFS/GFS All of the above applications generate high random read/write IO and require low latency. Match use cases to flash implementations to deliver on performance promises at lowest possible overall system cost

WHY ARE RANDOM IOPS WORKLOADS CRITICAL? I/O workloads are either random (many concurrent accesses to relatively small blocks of data) or streaming (sequential data transfers) Historically, random access has been associated with transactional workloads, which often represent an enterprise s most critical IT operations Adoption of scale-out architectures with networked storage drivers for scale-out include server and desktop virtualization, database consolidation, complex analytics, and data warehousing Even workloads that appear to be sequential from an individual application s point of view actually become random as they interact with other workloads using advanced disk array capabilities like de-clustered RAID, thin provisioning, and automatic storage tiering

FUNDAMENTAL STORAGE PERFORMANCE CHANGES AVAILABLE Yesterday s High Performance Today s High Performance A single Hitachi Accelerated Flash storage module can deliver 500X more IOPS than a single high-performance disk drive
