# Before you start

> Pre-deployment checklist and environment verification for the SAP HANA TDP integration on Linux.

Verify your environment meets these requirements.

## Supported hardware

* CryptoHub `7.2.0.7` or later.

## Supported operating systems

* A Linux distribution supported by both SAP HANA and the CryptoHub Linux TDP agent (for example, RHEL 9).

## TDP agent and driver

* The CryptoHub Linux TDP agent (`ftdp`) and the `fesfifs` kernel module (`fesfifs-dkms`).

<Note>
  The `fesfifs-dkms` package requires `dkms`, which is not included on the RHEL 9 installation media. On an unregistered, ISO-only, or airgapped host, enable EPEL or an equivalent repository that provides `dkms` before installing.
</Note>

## Required access

* An account on the CryptoHub with administrator privileges to deploy services and manage path rules.
* Root (or `sudo`) access on the Linux host running SAP HANA, to install the agent, load the kernel module, and manage mounts.
* The SAP HANA administrator user (for example, `<sid>adm`) and its group (`sapsys`).

## SAP HANA

* A running SAP HANA instance whose persistence base paths you can identify. You can look these up with:

  ```sql theme={null}
  SELECT KEY, VALUE FROM SYS.M_INIFILE_CONTENTS
  WHERE SECTION = 'persistence' AND KEY LIKE 'basepath%';
  ```

  The values of `basepath_datavolumes` and `basepath_logvolumes` are the directories this integration protects.

## Network and firewall

* Allow outbound connectivity from the SAP HANA host to the CryptoHub, specified by FQDN (for example, `cryptohub.example.com`) or CIDR (for example, `10.0.0.0/24`), so the TDP agent can reach CryptoHub for policy and key delivery.

<Warning>
  TLS inspection or SSL proxies can break mutual TLS handshakes. Exempt the CryptoHub FQDN(s) from inspection, and configure the CryptoHub with a FQDN so the exemption applies.
</Warning>
