Server Platform Requirements
General Assumptions
Open-Xchange App Suite Server (middleware services) is designed to run on physical servers or virtual machines of the same flavor. Cloud environments might be used in terms of Infrastructure as a Service (IaaS), meaning that all components need to be deployed in a classical manner on virtual machines.
This means in particular, but not only:
- Infrastructure is "quasi-static". We don't need to take into account things like VMs coming and going dynamically, dynamic IPs, volatile ("ephemeral") data
- "Database as a service" is not allowed. This typically is a highly customized "MySQL like" storage engine, and not a true MySQL, and we can't control flavor, version, setup, etc. If need for configuration changes is identified, we won't be able to change anything.
So to summarize: we expect any virtualized platform to behave and work just like a well-known non-virtualized / physical platform.
Especially we expect the virtual hardware to be not over-provisioned. Each VM must have dedicated resources with respect to CPU cores, RAM, IOPS, storage, network bandwidth, network latency, etc.
Network is expected to be flat, inside one datacenter, no multi-datacenter, no segments. No packet loss, low latency.
Disclaimer: All recommendations below are without guarantee and can differ for specific deployments. For mid- and large-scale setups a detailed deployment planning and sizing tests are mandatory and should be agreed on with OX Professional Services.
High Level Design / OS setup
Operate services separately (USM, Document/Image Converters) as described in Cluster Setup.
Clocks between all nodes must be synchronized (e.g. via NTP).
Open file/max process limits need to be adjusted properly. Based on the used Linux distribution and init system configuration will differ, see Resource Limits for further explanation.
Platform Architecture: 64 bit versions (x84_64) of the supported Linux distributions
Node Sizing
- Max. 8 GB heap per JVM + 4 GB system memory for other daemons and the OS (buffers, caches)
- 4 CPU cores (virtual, physical or hyperthreads)
- Disk space
- 5 GB for OS and software
2 * system memoryof free disk space (i.e. 12 GB RAM => 24 GB free disk space) for file spooling, log files, heap and core dumps
Untested/Unsupported Deployments
- Changes to Garbage Collector settings
- Running in containerized environments (Docker, rkt)
- Elasticity/High velocity of nodes going up and down: Services are sometimes stateful and demand static configuration
- Cloud platform services (PaaS) like database systems (for example AWS RDS)
- Multi-site active-active
