Requirements for the remote database servers
This section lists the requirements for the computers that you want to use as remote database servers. It is especially important to review these requirements if your organization has a database infrastructure that is centrally managed, where specific security policies might be implemented. Some of the requirements for installing HPC databases remotely might not comply with those security policies.
Each computer where you want to install an HPC database must meet the following requirements:
- SQL Server 2008 SP1 must be
installed and running on the computer.
Important - The Express edition of SQL Server 2008
is supported; however, it is not recommended for HPC clusters that
have more than 256 nodes. If you decide to install the Express
edition of SQL Server 2008 and you are deploying a large
cluster, be aware that its database size limitation is
4 GB.
- The Compact 3.5 edition of SQL
Server 2008 is not supported.
- The Express edition of SQL Server 2008
is supported; however, it is not recommended for HPC clusters that
have more than 256 nodes. If you decide to install the Express
edition of SQL Server 2008 and you are deploying a large
cluster, be aware that its database size limitation is
4 GB.
- One or more instances of SQL
Server 2008 SP1 must be available on the computer, and
these instances can be used to create the HPC databases.
- A login can be created on each instance for
the domain account that will be used for the installation of the
HPC cluster and for any HPC administrators that are added to the
cluster in the future.
- The sysadmin server role can be
assigned to all logins that are created for the HPC cluster.
- Each instance can be configured to be
accessed remotely.
- Firewall exceptions can be created on the
computer to enable remote access to the databases.
- The computer has storage and processing
resources to efficiently handle the new databases.
Requirements for the network connection between the head node computer and the remote database servers
This section lists the requirements of the network connection between the computer where you install HPC Pack 2008 R2 and each remote database server.
The network connection must meet the following requirements:
- The head node computer and the remote
database servers must be connected to the same domain or to trusted
domains.
- The head node computer must be connected to
all the HPC networks.
