At a transport level, FlashArray sends data over dedicated NFS network ports (2049, 111, 4001, and 4045) to Access. The ownership of the NFS exported share belongs to a FlashArray user with a user id and group id of 1000, hence, limiting the access of the contents to this specific user. For enhanced security, the Access Appliance also has encryption capabilities in conjunction with an external Key Management System (KMS). The appliance encrypts the volume that the “file system” resides on. An external KMS such as IBM KMS is required to create the keys for the encryption.
