Cisco SAN Analytics is the industry's first and only integrated by design architecture that provides you deep visibility into every transaction of your block storage traffic and IO flow, natively within your site. It requires no external hardware Apps, appliances or SPAN related traffic. Cisco SAN analytics is fully integrated with MDS 9000 switches and Cisco Data Center Network Manager or DCNM. By enabling one command, you will get the full view of the entire infrastructure. Overall, Cisco SAN Analytics is simple and affordable like no other solution before.
Todays, enterprises need "at-the-scale" visibility but it not easy as there are so many types of servers, uplink systems, storage arrays, different vendors' architecture and etc. To solve complex troubleshooting, Cisco came with a simple yet extremely powerful approach. Since the IO command between the compute and the SAN storage layers are transported by the storage fabric, the MDS 9K switches do a deep packet inspection of the frames all the way to the Fibre Channel, SCSi/NVMe headers to calculate storage performance metrics.
These metrics are calculated natively within the switches in absolute real-time. In fact, some of the metrics have a granularity in microseconds. The storage performance metrics are calculated by inspecting wired data, so there is no dependency on the whole operating systems, virtualized or bare-metals or storage array architectures. If the application accesses storages using standard based SCSi and NVMe commands, Cisco SAN Analytics sees those transactions and reports the oral health.
At any instance, the Cisco MDS switches are collecting millions of performance metrics, but actionable insights are needed. For this matter, switches export the data to the Cisco DCNM for advanced analytics, end-to-end correlation and long-term trending.
