FluidFS Version 6.0.300135 New Features and

Enhancements

Version 6.0.300135 provides the following new features and enhancements:

• Ability to manage FluidFS systems using Dell Storage Manager version 2018 R1

• FTP command support for the size request

SCSI Unmap Enhancement

SCSI Unmap is a FluidFS attribute that controls the way deleted file space is handled. When disabled, the SCSI Unmap setting will keep

deleted file storage within the FluidFS storage pool. This means that when files are deleted, their storage pages remain “used” for the

Storage Center management tools. When SCSI Unmap is enabled, deleting files also frees the storage pages at the block level and the

storage will be marked as white space and able to be utilized by the Storage Center system for other block clients. SCSI unmap is now

enabled by default when installing a new appliance.

SCSI unmap is now enabled by default when installing a new appliance.

NOTE: If you have any systems that were deployed using a version earlier than 6.0.300135, check and ensure that SCSI Unmap

had been enabled to prevent unnecessary space from being consumed.

To enable SCSI unmap:

1. In the Storage view, select a FluidFS cluster.

2. Click the File System tab.

3. In the NAS Pool Advanced Status area, click Edit Space Reclaming Settings.

4. To enable SCSI Unmap, select the Enable SCSI Unmap (TRIM) checkbox.

5. Click OK

FluidFS Version 6.0 Features and Enhancements

Version 6.0.003169 introduced the following features and enhancements. For more information and detailed instructions about using these

features, refer to the Dell Storage Manager Administrator’s Guide.

Multitenancy

Multitenancy enables a single physical FluidFS cluster to be connected to several separated environments and manage each environment

separately. FluidFS v6 supports up to 100 tenants.

Multitenancy Data Access – Access through a VIP enumerates the SMB shares and NFS exports that belong to the tenant and connect

to these shares and exports. Each tenant has separate access control settings, including the ability to join the same or separate Active

Directory domains.

Multitenancy and Data Protection – When the multitenancy feature is enabled on the local or partner systems, the global administrator

has the ability to create a partner relation between the tenants on the source system and tenants on the remote system.

NOTE:

The NAS Volume Subnet Restriction feature has been deprecated starting in FluidFS v6. Use the multitenancy

feature instead to restrict access to NAS Volumes.

SMB3.1 and SMB3.1.1

SMB protocol 3.1.1 dialect adds pre-authentication integrity, cipher negotiation, AES-128-GCM cipher and cluster dialect fencing. Pre-

authentication integrity improves protection from an attacker in tampering with SMB’s connection establishment and authentication of

messages. The cipher can now be negotiated during connection establishment. In addition to AES-128-CCM cipher used at SMB 3.0.x,

Windows 10 (and Windows Server 2016) added AES-128-GCM cipher in SMB 3.1.1. The GCM mode offers a significant performance gain.

SMB3 Multi-Channel

FS8600 supports multi-channel for SMB 3.x clients (Windows 8 and later, Windows Server 2012 and later). This feature allows clients to

create multiple TCP connections for a single SMB session. Multi-channel can improve performance by increasing the number of
