Albireo Deduplication for Solid State Devices
Solid State Devices (SSD) are the performance leader in IT. SSD’s accelerate application performance because of the superior I/O performance they deliver compared to spinning disk. Mission-critical applications in the enterprise such as database indexing, online transaction processing, desktop and server virtualization, front-end Web serving, and key infrastructure offerings (such as email and messaging) are targets of SSD deployments.
Over the past few years, the cost of high-performance storage has dropped significantly relative to performance density. The main driver for this cost reduction is the emergence of solid-state devices (SSDs).
When deduplication technologies are applied to Solid State Devices the effective costs become even more aligned with spinning disk. Additionally, write performance is improved because less data is being written relative to the amount of data stored. Vendors are just beginning to offer deduplication in these environments today, as deduplication becomes the enabler that closes the cost gap that has been an inhibitor to more widespread adoption. Deduplication technology designed for spinning disk-based primary or backup storage does not readily apply to devices based on flash technology. Permabit Albireo for Enterprise Flash has been designed specifically to meet the demands of these I/O intensive devices using patented technology and algorithms that optimize resource efficiency in solid state environments.
Solid State Devices (SSD) typically come in one of two form factors:
- Traditional Disk Drive - These units provide a traditional drive form factor and support industry standard SAS/SATA interfaces. Performance for these devices is typically limited by the interconnect speed, but they can be easily deployed in existing storage solutions making them an integral part of hybrid storage solutions.
- PCIe – Most often is a card that attaches to the PCI port and has been differentiated from the disk based form factor because it addresses the I/O latency gap between traditional storage SAS/SATA interfaces and flash by delivering PCI bus enabled speed
Business Benefits
- Lowers both cost per write operation and effective cost per GB stored
- Improves quality of service and increases customer satisfaction
- Reduces maintenance costs because less storage is needed
- Provides competitive differentiation
Technical Benefits
- Increases performance by lowering the cost per write operation, increasing effective DRAM cache size and reducing average read latency by utilizing algorithms designed specifically for flash environments
- Increases reliability by reducing the number of writes (translates to increased write cycles)
- Increases efficiency by lowering the effective cost per GB stored
