Deployments, Reliability, Performance and Scalability (EN)

Deployment Options

As communications within any enterprise is critical for day-to-day operations, RackCorp recommends a multi-zone deployment for the RackCorp UMPUMS product.

A typical 2-zone deployment looks like this:

RackCorp UMPUMS is designed to be run in HOT-HOT format, but can also be run in HOT-WARM format between the sites.

The redundancy zones are not restricted geographically, however network latency between the zones is recommended to be under 80ms, especially on large environments.  S3 platform is assumed to already be redundant in the above deployment option.

 

Scalability

The service will scale according to the disk IOPs and network bandwidth/latency between sites.  Primarily the disk IOPs of the COURIERIMAPXX servers are critically important to email performance, and S3 performance is critical to the cloud storage services.  These tend to be the most significant bottlenecks other than the expected network bandwidth.

Overall great care has been taken to build high-performance into the UMPUMS

 

"Well-Performing" System Requirement (Examples)

Every enterprise is different in regard to user-activity and media usage.  The below serves only as a "typical" ISP-based guideline.  RackCorp recommends to have 3x the capacity noted to run a fast user-engaging environment.  As speed drops, users tend to use third parties again which may damage the intention of using a data-sovereign solution.

Number of Users (Configured)	Disk IOPs (Single-site)	Average Network Bandwidth
500	800	3 Mbit/s
1000	1,000	5 Mbit/s
5000	3,000	40 Mbit/s
20000	12,000	160 Mbit/s
50000	30,000	250 Mbit/s
