Who uses a Flash Server and Why?
All-Flash servers are ideal platforms for hyper-convergence and latency sensitive applications. Data scientists, cloud and HPC workloads are all ideal candidates for a flash server. While the cost per gigabyte of flash storage exceeds that of traditional hard drives, costs have decreased significantly making All-Flash server configurations very compelling for these workloads.
How Flash servers work?
An All-Flash server can be set up either with SAS-based SSD drives in a traditional All-Flash array or, lately, utilizing non-volatile memory or NVMe directly connected to the PCIexpress I/O on the server. In either case, the IOP performance and throughput greatly exceeds that of traditional rotating media.
Benefits of Flash Servers
The greatest benefit of utilizing an All-Flash server equates to performance in both IOPs and throughput. Latency, or the time it takes for a server to answer a request, is greatly reduced by the read/write speed of the All-Flash storage versus magnetic hard drives. Capacity and wear tracking for SSDs is at a point where an All-Flash configuration meets the needs of most workloads with few exceptions.
