Volumes Recycle Bin

The Recycle Bin is enabled by default, but you can also disable it. When enabled, deleted Volumes are kept in the Pool’s Recycle Bin and can be restored. If the Recycle Bin is disabled deleted Volumes are immediately destroyed and cannot be recovered.

Public IPs

This displays any Public IPs assigned to the Controllers. A Public IP allows host connectivity from outside of the VPSA VPN.

Datamover Concurrency Level

You can control the load allowed for datamovers such as mirroing, cloning, etc... by setting the concurrency level. Default is Medium

Zadara Container Services Engine

This displays which, if any, ZCS Engine has been configured via the Provisioning Portal.

Zadara IO Engine

This displays which VPSA IO Engine (Model) has been configured via the Provisioning Portal.


Security

image125

Password Policy

The VPSA Admin can control the VPSA Password expiration policy and password history policy.

Dual Factor Authentication The VPSA Admin can force all users to login to the VPSA GUI using dual factor authentication. For details see: Dual Factor Authentication

Global VPSA CHAP

This gives you a uniform username and password to use when you create Servers.

Encryption

This sets the Volume encryption password for the VPSA’s data-at-rest encryption.

For more information on managing encrypted volumes see Managing Encrypted Volumes .

Support Privilege Access

This controls the ability of Zadara support engineers to access the VPSA virtual controlers with privileged rights. Only the VPSA Admin can change this setting. If enabled, the VPSA Admin gets notification every time the privileged access is used.

Cloud Admin Access

This sets the cloud admin’s VPSA GUI access (via the Command Center) to Enabled/Disabled status.

IPsec Key

This displays the key to be used when configuring IPsec tunneling for secured host connections.


NAS

image126

NFS Domain

This sets the domain name for NFS shares. This defaults to localdomain. (NFS4 Only)

NFS ID mapping

If enabled, each UNIX (Linux) User must be defined as a NAS User in the VPSA. If disabled, UNIX Users are authenticated on the UNIX host side.

SMB NetBios Name

This gives the VPSA Admin the option to change the default name of the VPSA as it apears in Active Directory. This field must be modified before the VPSA joins AD.

SMB Character Set

This gives you the default Character Set for SMB/CIFS Volumes. If you plan to use filenames with different encoding in the filename (other than English), you may want to change the Character Set. The default value is UTF-8. Changing this value while clients are connected will cause them to temporarily lose access to all SMB shares.

Defragmentation

You can enable/disable background file system defragmentation. This also allows on-demand defragmentation.

File System Trim

This

  • Periodic fstrim is triggered every weekend (On Saturday 00:00)
  • Can be manually started and stopped via the settings page.

Metering

The VPSA provides an option to download its performance metering database which contains per-minute performance statistics about all active and monitored Objects – Drives, RAID Groups, Pools, Volumes and Servers. The database is downloaded in a binary format and is accompanied with a tool (meter2csv) to convert the raw binary database to a csv formatted file.


Container Service

image127

Container Network

This displays the internal IP range of the ZCS and is accessible only by the host VPSA.

Exposed Ports

This displays the Ports ranges that are exposed for host access.

Image Repository

This displays the Status, Pool and Capacity of the Image Repository that stores all of the ZCS containers and images.


Network

VPSA support Jumbo Frames. MTU size can be set to values from 1500 to 9000 for both the Front End (data) network, and the public network & VNIs (Public & VNI network MTU). Default is 1500 for both.

Note

Changing the MTU can be disruptive for ongoing traffic. Existing iSCSI server sessions may require a restart for the new MTU setting to take effect.


Diagnostics


Network Diagnostics

A common issue storage administrators pace is the ability to verify connectivity between the storage system and the servers using the storage. Connectivity might be even harder to verify in a cloud environment, depending on the network topology. VPSA Network Diagnostic allows you to check connectivity over the selected network to any server:

  • Go to the Diagnostics page.
  • Select the VPSA network interface
  • Enter the target IP address of the server in question.
  • select if you want to ping the server, traceroute or both
  • Click Run.

It take a minute or so until the results show up in the output box.
