- Compatible with both Gen1* and Gen2 hardware
*Only compatible with Gen1 after the customer has upgraded to the Embedded IO Module v2.
New Embedded IO Module v2:
- Allow for new Embedded IO Module v2 to be used in PowerStore Gen1 hardware. The Embedded IO Module V2 has one 4-port card slot used primarily for intercluster connectivity, one 2-port card slot primarily used for 100GbE expansion enclosure connectivity, and two embedded 1GbE ports.
- Provides support for a new Embedded IO Module v2 to be used for PowerStore Gen1 hardware. This new IO Module allows for better performance and support for a 100GbE Mezz to be used with the new NVMe expansion enclosure.
New 100GbE optional IO cards:
- Customers can purchase either one or two pair of 100GbE optional IO cards for frontend connectivity. Dual 100GbE ports that can be used to serve front-end Ethernet traffic.
- Supported for all PowerStore 1000-9000 and 1200-9200 models
- PowerStore 500 will not be supported due to performance limitations
- The module hardware is a ConnectX-5 based WaterskyX 2-Port 100GbE module
- For use in I/O Module Slot 0 only.
Native Block Metro Volume:
- This feature provides support for VMware vSphere Metro Storage Cluster.
- Provides Active-Active IO to a Metro Volume across two PowerStore Clusters
- Supports FC/SCSI or iSCSI connected VMware ESXi hosts
- Non-Uniform and Uniform host connectivity
- Used for disaster avoidance, application load balancing and migration scenarios.
You can use two PowerStore systems connected in a metro cluster configuration to increase a block volume’s availability. The primary application target is VMware vSphere Metro Storage Cluster.
Space Utilization Enhancement:
- PowerStore supports mixing Dynamic Resiliency Engine (DRE) RAID widths within a resiliency set.
- If an appliance was initialized with a certain width, but enough drives have been added to the system to support a larger width, the larger width may be used for new data allocations.
- Using the larger width improves the usable capacity of the appliance in scenarios where significant additional capacity is added after initialization.
- Single drive failure tolerance – 4+1 and 8+1 widths can be mixed in a resiliency set (Resiliency set maximum drive count = 25 drives)
- Double drive failure tolerance – 4+2, 8+2, and 16+2 widths can be mixed in a resiliency set (Resiliency set maximum drive count = 50 drives)
Add Appliance Without Requiring NDU:
- Allows a new PowerStore appliance with a different PowerStore OS version to be added to an existing PowerStore cluster without completing the prerequisite steps of manually synching the PowerStore OS version on the new appliance with the version on the existing cluster.
- Simplifies the Add Appliance process by automating the steps for synching the PowerStore OS version on the new appliance.
- If unconfigured appliance is not at the same version of code, user will perform a sync operation.
- PowerStore primary appliance will copy its image to the unconfigured appliance.
Enhancements to the SmartFabric Storage Software (SFSS) integration for NVMe/TCP:
- Adds support for the automatic discovery of the SFSS/CDC IP and sending a kickstart discovery request command to initiate pull registration.
Internal Network Enhancements:
- This ICM/ICD network for a single PowerStore T appliance now routes internally (within the appliance backplane).
- System bond is only required with Clustering
- A single PowerStore T appliance in Unified mode no longer requires system bond cabling.
- System bond is now optional with iSCSI, replication, import, and NAS.
- Added the ability for the user to aggregate front-end Ethernet ports into a LACP bond.
- Scale NAS storage to additional ports and IO Modules.
- Separates NAS server traffic to different ports and IO Modules
- Improved throughput and high availability for NAS
- User created Link Aggregation is supported for PowerStore T only
- Support aggregating 2 to 4 ports at once. Ports must have the same speeds, duplex settings, and MTU.
- User created Link Aggregation is only supported for NAS interfaces (No support for block resources at this time).
New Asynchronous Replication:
- Add support for asynchronous replication for PowerStore File systems.
- Configure Storage Network (data transfer). Storage Network is an existing PowerStore concept used for iSCSI and NVMe/TCP host traffic, replication, and native block import. File Replication uses the Storage Network tagged for replication (does not require a new Storage Network, existing networks can be leveraged).
- Configure File Mobility Network (control plane). File Replication requires connectivity between source and destination SDNAS. SDNAS containers on each cluster communicate control information over this network. Only one File Mobility Network required per system.
A public routable network based on the 1 GbE management ports. File Mobility Network is also leverage for Native File Import.
- Replication provides business continuity by copying data to a remote system, enabling data access in situations where the primary system is not accessible.
File Level Retention:
- File Level Retention (FLR) enables locking files to prevent them from being modified or deleted for a specified retention period. It’s also known as Write Once, Read Many (WORM)
- FLR Enterprise (FLR-E): Does not prevent file system (FS) deletion by storage administrators if FS has locked files.
- FLR Compliance (FLR-C): Prevents FS deletion by storage administrators if FS has locked files (Dell support will not be able to delete an FLR-C FS with locked files).
Common Event Publishing Agent (CEPA):
- Supports CEPA for NFS and SMB file system level event publishing (File System Auditing).
- CEPA allows third party applications to take event driven actions on PowerStore to prevent ransomware, manage user access, and other analytics use cases
- Provides the integration point for vendors such as Varonis, Stealthbits, and DefendX
- Audit events such as open, create, delete, rename, close, etc.
VMware File Enhancements:
- Add an optimized File System for VMware workloads and plugin support for VAAI and VSI.
- Optimization of VMware File Systems performance. VAAI support for advanced features, such as Fast Clone.
- New filesystem type called VMware File System
- VMware File Systems should only be used as VMware NFS Datastores
