Document Number: 680-050-018 Rev. F 2019 - 06 Storage Manager 2018 R1 Release Notes Storage Manager allows an administrator to manage and monitor multiple Storage Centers, PS Series groups, and FluidFS clusters. Storage Manager 2018 R1 introduces new features and enhancements, and fixes issues present in the previous release. Current Version: 2018 R1.20 Release Date: 2018-11 Previous Version: 2018 R1.
Product Versions NOTE: Storage Manager 2018 R1.10 can be used to connect to a storage system running Storage Center 6.6 and update it to a later supported version of Storage Center PS Series group firmware 7.0–10.0 Dell FluidFS 6.0.300135 NOTE: You must update FluidFS firmware to 6.0.300135 before updating to Storage Manager 2018 R1. Microsoft System Center Virtual Machine Manager (SCVMM) 2012, 2012 SP1, 2012 R2, and 2016 VMware vCenter Site Recovery Manager (SRM) 5.8, 6.0, 6.1.1, 6.5, and 8.
Component Requirements NOTE: Linux versions of the Storage Manager Client support only 64-bit microprocessors. Software Linux VM Access Client Web browser Microsoft .NET Framework 4.0 (Windows only) • • VMware vSphere Web Client Hyper-V Manager Any of the following web browsers: • • • • Google Chrome Internet Explorer 11 Microsoft Edge Mozilla Firefox NOTE: Google Chrome is the recommended browser.

Component Requirements Web browser Any of the following web browsers: • • • • Google Chrome Internet Explorer 11 Microsoft Edge Mozilla Firefox NOTE: Google Chrome is the recommended browser. Other web browsers might work but are not officially supported.
Server Agent Requirements The following table lists the requirements for running the Storage Manager Server Agent on Windows servers. Component Requirements Operating system Any of the following 64-bit operating systems (with the latest service packs): • • • • Windows Server 2012 (full or core installation) Windows Server 2012 R2 (full or core installation) Windows Server 2016 Windows Server 2019 CPU 64-bit (x64) microprocessor Software Microsoft .NET Framework 4.
Conservation and Emergency Mode The Conservation Mode threshold has been changed to 0.5 percent of the usable space in a storage system. The minimum amount of usable space might range from 100 GB to 2 TB, depending on size of the storage system. When a storage system enters Conservation Mode, the volume queue depth is limited to reduce the rate at which servers consume space. Snapshots no longer expire automatically when a storage system is in Conservation or Emergency mode.
Distributed Sparing Distributed sparing allocates spare disk space across all drives rather than reserving an entire drive as a spare. Distributed sparing enables the storage system to use all disks in a balanced and optimized manner, which ensures the fastest recovery time following a drive failure. After a storage system is updated to Storage Center 7.3, it automatically manages all spare drives and prompts the user to enable the Spare Optimizer feature.
Replication for SCv2000 Series Storage Systems Replication is now supported between SCv2000 Series storage systems and the following storage systems: • SC9000 • SC8000 • SC7020F • SC7020 • SC5020F • SC5020 • SC4020 • SCv3000 Series SRA Improvements Changes made to SRA code and API resolve issues found in SRA operation, resulting in: • Improved SRA error handing and reporting. • Better stability in multi-threaded environment. • Resolution to generating duplicate volume IDs.

An extra artifact is that a VVol datastore is identified with improper size of 0 byes.
Issue Description • • Changing a storage container’s Data Reduction profiles might cause future fast cloned VMs to be created with mismatched Data Reduction profiles for the config and data VVols. If a user applies a VM Storage Policy to the original VM, the same changes apply to the data VVols of the fast clone VM and conversely. Workaround: None DSM-14806 Migrate or Clone operations on virtual machines with snapshots might fail if not enough space is available in the VVol datastore hosting the VM.
Issue Description DSM-11945 Even after unregistering VASA, powered-off VMs are accessible and VVol datastores are active.
