Speed is one of the defining success factors when it comes to the user experience. How fast an application or database reacts is strongly dependent on its ability to process, store, and retrieve data.
Quick response times make a lasting impact on today’s low latency-demanding business services. While data processing is dependent on the application, how quickly data can be stored and accessed can be optimized by enhancing the performance of the underlying storage hardware.
Your SAN infrastructure plays a key role in impacting application responsiveness. You could be using SAN storage with only hard disk drives (HDD), or solid-state drives (SSDs) or a combination of both.
Typically, IT organizations move from HDDs to SSDs, or add more SSDs to improve a SAN array’s performance. Using all-flash arrays can dramatically augment storage performance, but it can also inflate the IT budget. Then there are technologies like NVMe and Intel Optane which further enhance the storage processing speed and performance.
DataCore SANsymphony is a high-performance caching engine, that can take commodity hardware and turn it into performance rich SAN.
Thanks to SANsymphony we are able to deliver scalable, cost-efficient and future-proof high-performance storage architectures to our customers running SAP HANA workloads. Storage is smarter, more powerful, and more efficient with DataCore.

With SANsymphony, we could use less expensive disk in place of enterprise-level disk and achieve the same performance.
How RAM caching speeds up read and write operations:
- Read processing is accelerated by pre-fetching anticipated blocks from the disk (based on earlier reads from the disk) into the read cache, which makes reads much faster.
- Write coalescing technology is used to reorder random writes that are held in cache, and to eventually write them to the disk in large sequential stripes. This avoids waiting on disk for every write operation and speeds up the overall writing process.
Use SANsymphony, in combination with existing storage and the caching, remarkably enhances the speed and performance of your SAN infrastructure.
Convert Random Writes into Sequential Writes to Accelerate Performance
A known performance problem, especially with HDDs, is when data is written randomly instead of sequentially. For every random write, the HDD must reposition its head, which takes time and delays overall write time and affects IOPS.
SANsymphony offers the capability to convert random writes into sequential writes with a random logical addressing. This organizes all inbound writes into a sequential pattern on disk, while the data random layout perception remains. Because the disk head does not need to be repositioned for every write, SAN performance is greatly improved.
Emergency Communications of Southern Oregon had a Microsoft SQL-based dispatch application that was running too slow. This slowed down the speed at which police, fire and other emergency services could be sent to people that needed help, putting lives in jeopardy.
With DataCore, they were able to improve SQL Server response times by 20x. This improved performance also enabled them to consolidate their infrastructure and reduce costs. The 200 millisecond latency has gone away now with DataCore running.
DataCore SANsymphony: Much More Than Performance Acceleration
In addition to effecting performance gains, SANsymphony software-defined storage helps organizations reduce storage-related downtime and improve business continuity. Moreover, it enables seamless data migration between disparate storage systems while simplifying storage management.
Delivering uniform data services across heterogeneous storage, SANsymphony provides IT teams with the flexibility to mix and match storage hardware of their choice. This allows maximizing investments in the existing infrastructure before purchasing new and costly SAN arrays.
