SEPATON S2100-ES2 Performance

November 14, 2008 – 3:26 pm

The SEPATON S2100-ES2 was designed for speed. Our solution is based around the concept of a unified appliance which provides one GUI for managing and monitoring all embedded hardware. We also automate the disk provisioning and configuration to provide consistent scalability and performance. The result is an appliance that can easily be managed by an administrator who understands tape and wants to avoid the traditional complexities of disk.

Our performance is quite simple to understand. We use a grid architecture which means that all nodes can see all storage and can access the same deduplication repository; you can backup and restore from any node. Today we support five nodes with DeltaStor while the VTL supports 16. We will be adding support for larger node counts in the near future. Each node provides an additional 2.2 TB/hr ingest and 25 TB/day deduplication performance. The appliance deduplicates data concurrently that means that backups and dedupe occur simultaneously with no performance impact. Let’s look at the actual numbers.

Backup Speed

Deduplication1 Node5 Nodes
Off1.1 TB/hr (Single Stream)
2.2 TB/hr (Aggregate)
1.1 TB/hr (Single Stream)
11.0 TB/hr (Aggregate)
On1.1 TB/hr (Single Stream)
2.2 TB/hr (Aggregate)
1.1 TB/hr (Single Stream)
11.0 TB/hr (Aggregate)

Restore Speed

On*1.1 TB/hr (Single Stream)

11.0 TB/hr (Aggregate)

* Forward referencing enables us to provide this restore performance on deduplicated data. The newest backups will always provide the fastest performance.

Deduplication Speed

125 TB/day

A few additional points to consider:

  • Our single stream performance is based on individual ports. Thus we can ingest at 1 TB/hr single stream per port; if you have 10 ports, you can have 10 simultaneous 1 TB/hr streams.
  • We do not need a separate “garbage collection” process as required by most other solutions. This process is included in our performance metrics. Most vendors require a separate process and exclude its impact when providing performance metrics.
  • The S2100-ES2 includes hardware compression on both deduplicated and non-deduplicated which reduces footprint by about 2:1. Most other vendors either use software compression or use hardware compression selectively. (e.g. on the deduplication repository only.)
  • The 5 node system can address environments with 100 + TB in one system image and deduplication repository. Protecting the same environment with competing solutions will require multiple independent systems.
