ITA System requirements

ITA 9.1.1 and newer supports installation on RHEL 8.x and Rocky Linux 8.x RHEL 9 is not yet supported. Installing ITA 9.1.0 on a Red Hat operating system is not supported.   IMPORTANT: To install ITA 9.1.x on VMware, plan to use VMware ESXi 6.5 U1 or newer. Otherwise, you may see a kernel bug error in CentOS 8.x. See VMware KB article https://kb.vmware.com/s/article/2151480 for more information.   These system specifications are recommendations for your IT Advisor system configuration in general. The performance and operation of the system depends largely on the nature of the configuration, such as:    Number and population of racks Number and nature of integrations to external systems Number of devices and number of data points stored on these Power path configuration (one big, several small, across rooms, etc.) Concurrent and total users of the system and nature of their work cycle   If ITA is running on lower specification servers than recommended, users may experience long response times or timeout issues. In addition, the server may not be able to process scheduled jobs in a timely manner.    Recommended server hardware for IT Advisor on-premises   ITA on-premises requires a dedicated server, either hardware or a virtual environment. The operating system is included in the installation.   Recommended IT Advisor server configuration   Server requirement guidelines (minimum)   CPU: 4 cores minimum. We recommend 8 cores Memory: 16 GB RAM (absolute minimum requirement) 200 GB storage, speed minimum 170 MB/s Disaster recovery network: 10 Mbps with low latency <100 ms    Note: If you're installing ITA on-premises on an existing server, note that ITA claims almost all memory (JVM about 8 GB and Postgres about 6 GB alone). You might experience issues if you have other applications running on the server, such as surveillance and monitoring agents.   Server requirement guidelines for 10,000 racks across 200 rooms with 30 concurrent users   8 CPU cores 32 GB RAM 200 GB storage, speed minimum 170 MB/s   Server requirement guidelines for 20,000 racks across 400 rooms with 30 concurrent users   16 CPU cores 64 GB RAM 200 GB storage, speed minimum 170 MB/s   RAID systems   Hardware RAID controllers are recommended. We tested hardware controllers in the DELL x20 series, IBM M4 series, and HP G8 series. Be aware there might be hardware RAID controllers that we have not tested in special configurations.   Not supported:   Generally all software RAID controllers HP RAID Controller B-Series DELL RAID Controller S-Series   Security configuration   For information about security configuration, see here.   IT Advisor server communication   For information on server communication, see here.   Recommended IT Advisor desktop client configuration   For minimum recommendations for running ITA, see here.   You must have local administration rights on the client computer during installation, first login, and license upgrade.
