POSIX Client Specification

Project
Specification
Description
Single GooseFSx instance supports POSIX client count
4096
A single GooseFSx instance can be mounted by 4096 POSIX clients simultaneously.
Number of GooseFSx instances that a single POSIX client can mount
1
A single POSIX client can only mount one GooseFSx instance.
Note:
Since unmounting by the client is an asynchronous operation and takes some time to complete completely. Therefore, it takes more than 10 minutes for a POSIX client to unmount a GooseFSx instance before it can be remounted; otherwise, mounting fails.
Minimum configuration for a POSIX client
4 core 8 GB
Recommended minimum configuration for a POSIX client: 4 cores, 8GB memory. The available memory space of the client must be greater than 2GB to avoid deployment failure caused by insufficient available memory.
Note:
If this table cannot meet your needs or you have other requirements, you can consult online customer service for help.
Do not delete or overwrite the authorized_keys file of the POSIX client. Recommend using the ssh copy command to append write the authorized_keys file. Do not use the scp command to overwrite write the authorized_keys file.

POSIX Client Security Group Rules

The POSIX client needs to allow the following ports to communicate with GooseFSx. For relevant guidelines, please see Configure Security Group. If you also set up a security group with a denial policy for the POSIX client, please ensure that the POSIX client security group rules are not denied.
Protocol
Direction
Port
IP
TCP
inbound rule
22,1191,4242,4243,4739,8445,9085,9250,9251,9980,10080,55533,60000-61000
All IPs in the VPC to which GooseFSx belongs
UDP
inbound rule
4739
All IPs in the VPC to which GooseFSx belongs
ICMP
inbound rule
ALL
All IPs in the VPC to which GooseFSx belongs
Note:
Port 22 is the default port number used for SSH mutual trust communication between the POSIX client and the client management node. If it does not meet your requirements, customization is supported, and available ports can avoid the TCP ports allowed by the POSIX client's security group rules.
For example, if you customize the port to 2008, 22 will be replaced with 2008 and appear in the POSIX client security group rule.

GooseFSx Occupied VPC Subnet IP Address

To enable communication between hosts in the Customer VPC and GooseFSx, the GooseFSx file system will occupy a certain number of IP addresses in the VPC subnet. The larger the GooseFSx capacity, the more IP addresses are occupied, as follows:
Model
Number of Occupied IP Addresses
Description
C50.T3
1 IP address per 3 TiB
9 TiB capacity occupies 3 IPs
C50.T12
1 IP address per 12 TiB
36 TiB capacity occupies 3 IPs
C60.T2
1.5 TiB uses 1 IP address
4.5 TiB capacity occupies 3 IPs
C60.T12
1 IP address per 12 TiB
36 TiB capacity occupies 3 IPs
C70
1 IP address per 4.65 TiB
13.95 TiB capacity occupies 3 IPs
Note:
If the available IP addresses in this VPC are insufficient, it can cause GooseFSx expansion or creation failure. You can consult online customer service to ask for help.
