All of the hardware nodes in shared hosting cluster act as one giant computer providing a high level of performance and fault tolerance to our clients.
Hardware in cluster:
- Power: Each hardware node in the cluster has redundant Power Supplies connected to separate A or B UPS/Power systems.
- CPU: Currently we have 22 Cores of Processing power in the cluster (44 threads).
- Memory: 184GB of physical memory with error correction control is currently in the cluster. In 3 or 4 channel configurations, memory on the hardware nodes are for optimize performance.
- Network: Each hardware node in the cluster has at least:
- 2 redundant 1GB/s connections to the Internet with access to multiple peers.
- 4Gb/s connection to the storage cloud.
- 3Gb/s connection to the MySQL servers.
Cloud Storage:
- Redundant (RAID10) SAS Spinning disks (66 High Speed Drives) for data with redundant fast caching SAS controllers
- On Premise Backup Storage
- Off Site Backup Storage
Network:
- Redundant Switching and Routing
- Redundant Peers in multiple data centers across Canada
- IPv6 Available
Enhanced DNS servers:
- All hosting nodes push DNS zone file data to two head in DNS servers, dns1.nucleus.com and dns2.nucleus.com
- Each head end DNS server has extremely low CPU load and lots of available memory
- Each head end DNS server has redundant internet connections
Enhanced MySQL service:
- Dedicated MariaDB(MySQL) servers optimized and performance tuned monthly to provide our hosting clients with amazing low latency query response.
- by moving the bulk of our MySQL queries away from the hosting nodes we have greatly increased the amount of memory and CPU available for preforming hosting tasks on the nodes, as well as allowing a more dedicated use of resources for common tasks.
