Component Requirement Supported platform FS8600 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.

commands the client can transmit simultaneously, and by allowing clients to use multiple physical network interfaces. Administrators must enable SMB3.0 multi-channel if they want clients to be able to use it, as it might increase the number of TCP connections. Administrators should enable it only after verifying that the current SMB sessions are not near the supported limit for their FS8600 cluster.

• Data can be cascaded from the production cluster to a secondary cluster, and replicated from the secondary . This option reduces the load on the production cluster. These two options can be used together in order to comply with the organization’s disaster recovery topology and requirements Replication WAN Optimization When enabled, this feature optimizes replication by reducing bandwidth consumption. Data is deduplicated and compressed during replication without impacting the cluster performance.

Fixed Issues in FluidFS Version 6.0.300135 The following issues were fixed in FluidFS 6.0.300135: Area Description Data Protection FS8600 could not join or leave Active Directory if a trusted domain name contained an apostrophe, for example, John’s.. Active Directory status failed if the Domain Controller name contained an underscore.
PAGE 6
Fixed Issues in FluidFS Version 6.0.110054 The following issues were fixed in FluidFS v6.0.110054: Area Description Account Management and Authentication The preferred Domain Controller setting was not strictly enforced. Data Protection Following a Firmware update from v5 to v6, incremental NDMP backups failed frequently. Duplicate iSCSI IP addresses were falsely reported on multiple-appliance iSCSI systems. NetVault backups could not be partially restored after a firmware update to version 5.0.
PAGE 7
Area Description Maintenance Frequent power down activity might have prevented the cluster from starting up. If the Add Appliance procedure failed, the appliance could not be deleted. When renaming a UNIX file to the same name with different (upper/lower) case, Windows listed the file name with extra characters. Access to files originated in FluidFS v2 was denied, specifically if files pointed to hard links where the original entry was deleted.
PAGE 8
Limitations in FluidFS Version 6.0 The following limitations exist in FluidFS v6.0. Area Description System Management When you issue the hardware NAS-appliances status CLI command, it can take up to a minute for the information to be displayed. NIC status is not acquired directly from the operating system but from the relevant collector service agent, which has a polling interval of 60 seconds. Therefore, it is normal to have a one-minute delay in the CLI after an actual status change.
PAGE 9
Area Description System Functionality The current vSphere Web Client plugin, Compellent Integration Tools for VMware (CITV 3.1), does not support FluidFS v6 systems. A plugin that supports FluidFS v6 is planned for an upcoming release. The Dell Storage Manager client might lose connection to the Data Collector if it has been up and running for a period of time. If a connection loss occurs, the following error is generated: Unable to obtain Jdbc connection from DataSource.
