![]() Make sure that the firewall is permanently set to keep the required ports open, and will save these settings across reboots. If you use an antivirus scanner, such as Auditd or Antivirus, ensure the scanner excludes the /var/lib/gravity folder from its security scans. Anaconda recommends using the Network Time Protocol (NTP) to synchronize computer system clocks automatically over a network. When installing Anaconda Enterprise on a system with multiple nodes, verify that the clock of each node is in sync with the others prior to starting the installation process, to avoid potential issues. If adequate free space is not available in the /tmp directory, you can specify the location of the temporary directory to be used during installation by setting the TMPDIR environment variable to a different location. Storage and memory requirements #Īpproximately 50GB of available free space on each node is required for the Anaconda Enterprise installer to temporarily decompress files to the /tmp directory during the installation process. On-premises installations require servers with disks that support a minimum of 50 sequential IOPS. Hard disk manufacturers report sequential IOPS, which are different than concurrent IOPS. Cloud providers report concurrent disk IOPS. Master and worker nodes require a minimum of 3000 concurrent input/output operations per second (IOPS)–fewer than 3000 concurrent IOPS will fail. We strongly recommend that you set up the /opt/anaconda and /var/lib/gravity partitions using Logical Volume Management (LVM), to provide the flexibility needed to accommodate easier future expansion. This total includes additional space to accommodate upgrades, and is recommended to have available during installation as it can be difficult to add space after the fact. Network-Attached Storage (NAS) and Storage Area Network (SAN) solutions are susceptible to latency, and are therefore not supported. Core components of Kubernetes run from this directory, some of which are extremely intolerant of disk latency. This volume MUST be mounted on local storage. **NOTES regarding the minimum disk space in /var/lib/gravity: xfs - n ftype = 1 / path / to / your / device If your XFS filesystem has been formatted with the -n ftype=0 option, it won’t support d_type, and will therefore need to be recreated using a command similar to the following before installing Anaconda Enterprise: If you are installing Anaconda Enterprise on an xfs filesystem, it needs to support d_type to work properly. See Mounting an external file share for more information. Subdirectories of /opt/anaconda may be mounted through NFS. This total includes project and package storage (including mirrored packages).Ĭurrently /opt and /opt/anaconda must be an ext4 or xfs filesystem, and cannot be an NFS mountpoint. *NOTES regarding the minimum disk space in /opt/anaconda: To verify your systems meet the requirements, see Verifying system requirements.Īnaconda recommends having 1 master and 1 worker per cluster. To use Spark Hadoop data sources with Anaconda Enterprise, refer to Apache Livy and Anaconda Enterprise and Configuring Livy server for Hadoop Spark access. To use Anaconda Enterprise with a cloud platform, refer to Cloud performance requirements for cloud-specific performance requirements. For more information about sizing for a particular component, see the following minimum requirements: For more information, see Adding and removing nodes.Ī rule of thumb for determining how to size your system is 1 CPU, 1GB of RAM and 5 GB of disk space for each project session or deployment. After completing the installation, you can add or remove nodes on the cluster as needed. You are not bound to that initial configuration, however. ![]() When you initially install Anaconda Enterprise, you can install the cluster on one to five nodes. If you want to perform the system check yourself, before installation, you can run the command on your intended master and worker nodes after you download and extract the installer. The installer performs pre-flight checks, and only allows installation to continue on nodes that are configured correctly, and include the required kernel modules. There are cloud-specific requirements related to performance, however, so ensure your chosen cloud platform meets the minimum specifications outlined here before you begin. The installation requirements for Anaconda Enterprise are the same whether you choose to install the platform on-premises, hosted VSphere, or on a cloud server. For your Anaconda Enterprise installation to complete successfully, your systems must meet the requirements outlined below. ![]()
