New Features

New Features in Release 4.5(2e)

There are no new features in this release.

New Features in Release 4.5(2d)

There are no new features in this release.

New Features in Release 4.5(2c)

- Support for ESXi 7.0 U3—HXDP 4.5(2c) provides support for VMware ESXi 7.0 U3.

- Intel® Optane™ NVMe Cache support for DC-no-FI on M5 servers.

- New drives are qualified in HX 4.5(2c). For more information, see New Supported Drives.

New Features in Release 4.5(2b)

New drives are qualified in HX 4.5(2b). For more information, see New Supported Drives.

New Features in Release 4.5(2a)

The following new features are in HX 4.5(2a):

- HX Native Snapshots with ESXi 7.0 U2—introduces the following enhancements:

Beginning with HXDP version 4.5(2a) with ESXi 7.0U2, HX Sentinel snapshots are no longer created. Prior versions of HXDP will continue to utilize HX Sentinel snapshots. This is applicable to HX native snapshots created with the HX Connect UI, REST API, vSphere HyperFlex HTML client plugin, or stcli commands.

If there are no user or 3rd party backup snapshots, HX Sentinel snapshot(s), if present, are deleted when snapshots are created through the HX Connect UI, REST API, vSphere HyperFlex HTML client plugin, or stcli commands. This enables the usage of HX Sentinel-free HX native snapshots (VAAI).

If there are user or 3rd party backup snapshots, HX Sentinel snapshot(s) will *not* be deleted. We recommend a 1-time deletion of user and 3rd party backup generated snapshots to take advantage of the following improvements:

- Reduced stun times due to the delta disk being eliminated from all HX native Snapshot workflows.

- Improved quiescing support – vCenter will report quiesced snapshots as quiesced.

- Support for large VMDKs, and greater than 3TB VMDK disks.

- Support for VMs spanning HX datastores.

- VM snapshot consolidation is now a meta-data only operation and does not involve data movement. VM consolidation times are no longer proportional to VM I/O workloads.

Note

Cisco strongly recommends to utilize the HX Connect UI, REST API, vSphere HyperFlex HTML client plugin, or stcli commands to create snapshots and schedules. Using the vCenter Snapshot Manager bypasses these operations which are designed to minimize the cases where a user has to perform manual workarounds. Manual workarounds, such as adding the VM attributes snapshot.alwaysAllowNative or snapshot.ayncConsolidate flags, are neither recommended nor required.

For more information, see Managing HX Native Snapshots in the Cisco HyperFlex Data Platform Administration Guide, Release 4.5.

- 1:1 Replication with 2-Node HX Edge cluster—Support added for 1:1 replication with 2-Node HX Edge cluster. Supported configurations for native replication (NRDR 1:1) are 2N/3N/4N Edge and FI-based clusters to 2N/3N/4N Edge and FI-based clusters, including stretched clusters, all managed through HX Connect.

- Single Socket for Stretched Cluster configurations—allows users to optimize the hardware configuration cost and licensing cost for certain applications for a stretched cluster configuration. This support was introduced in HXDP 4.5(2a).

New Features in Release 4.5(1a)

The following new features are in Release 4.5(1a).

- iSCSI Support—HX 4.5(1a) introduces native iSCSI protocol support for workloads that require block storage (such as, databases) or shared disk access (such as, failover clusters). HX 4.5(1a) supports these software initiators: Windows Server 2016 and 2019, RedHat Enterprise Linux 7, Oracle Linux 8, Ubuntu 18.04 and 20.04. HX 4.5(1a) supports a rich set of iSCSI features, including: centralized login portal, direct logins, out-of-box Windows (DSM) and Linux (dm-multipath) drivers (active-active and active-passive), app-consistent and crash-consistent LUN clones, and target-side CHAP authentication.

- Cisco HyperFlex HTML5 Plugin for VMware vCenter—Provides users the ability to manage and monitor your HyperFlex clusters from the VMware vCenter Web UI. Additional functionally in version 2.1.0 includes:

- Snapshot Scheduler

- iSCSI Management

- Nodes and Disk View

- Virtual Machines Summary

- Events and Tasks

- VLAN Creation

- Rename Cluster

- HyperFlex Stretched Clusters

- Support for VMware vCenter Linked Mode

Note

HXDP Release 4.5(1a) is the final release that supports the Cisco HyperFlex Flash Plugin. This change coincides with the end of flash support in popular browsers. It is recommended that users upgrade to the Cisco HyperFlex HTML5 Plugin 2.1.0

- HyperFlex Edge 240 Full Depth Servers—New, full depth server offerings are now available for HyperFlex Edge. Both All-flash (HXAF-E-240-M5SX) and Hybrid (HX-E-240M5SX) configuration options are available. For more details, see the HyperFlex HX240 M5 Edge Hybrid and All Flash spec sheet.

- HX CSI Support—Cisco HyperFlex Container Storage Interface (CSI) adds support for the following features in HX 4.5(1a): Block access, Clone volume (when source volume is from the same Datastore), PV support with different file systems (Ext4, Ext3, XFS), Volume space statistics reporting per CSI specs, Multi-writer support (ReadWriteMany) for Block Mode only, Kubernetes 1.18 support, Kubernetes Cluster multi-tenancy target/lun masking using dedicated initiator group, Support for CSI 1.2 Spec APIs, Volume resize support for block mode volumes and ext3, ext4 filesystem volumes (expansion), CSI Plug-in installation and upgrade through Helm chart.

Note

When using HX CSI, if you don't need to preserve the persistent volume claim, see Cisco HyperFlex Systems Administration Guide for Kubernetes. If the persistent volume claim needs to be preserved then contact TAC.

- RAID Support for Boot Drives—Support for Hardware RAID M.2 boot drives in HyperFlex converged and compute-only nodes. Requires optional HX-M2-HWRAID controller with two boot drives. Existing single boot drive option remains supported.

- UEFI Secure Boot Mode—HX 4.5(1a) simplifies the hardening of hypervisor (ESXi) boot security by providing an automated workflow that non-disruptively changes the boot mode of converged and compute nodes in the cluster to Unified Extensible Firmware Interface (UEFI) Secure Boot, in which the chain of trust is anchored by a hardware trust anchor (for example the Cisco Trust Anchor module) built-in to UCS rack and blade servers. HX 4.5(1a) also allows UI and API-based queries of each node’s secure boot status so customers can audit the cluster’s security posture on-demand.

Note

UEFI secure boot should only be enabled on HX Edge clusters running Cisco IMC version 4.1(2a) and later. If secure boot is enabled on earlier Cisco IMC versions, secure boot will need to be temporarily disabled during firmware updates.

- vCenter Re-Registration—is a user-interface based feature that you can use to move to a new vCenter. You may need to re-register vCenter in the following scenarios: the Controller VM certificate is changed; it is recommended to re-register vCenter extensions whenever a vCenter upgrade is performed; re-registration is required when the extensions are manually removed due to misconfigurations.

- HyperCheck 4.5— The HyperCheck script is now included with the product and Rest APIs integration has improved performance. Run the hypercheck command to start the checks. You can perform HyperCheck at any time. It is recommended that you perform HyperCheck prior to upgrades. New features and checks include: Cluster Information table, DR (local and remote network) and SED checks for users who have them enabled. To update health check, use the framework provided in Intersight.

- Scheduled Snapshots on HxConnect—Provides users the ability to manage and monitor Snapshot and Schedule Snapshot from the HxConnect Web UI. New Functionally includes:

- Improved VM Summary - Added counts for total count for VMs with Snapshots and VMs with Snapshot schedules.

- VM Details - Introduce action buttons to Create HX Snapshot Now and Schedule Snapshot

- Compute node automated boot policy selection—Compute-only nodes are now easier to deploy with automatic detection and configuration of disk and boot policies based on the boot hardware discovered.

- Replication Factor 3 support for HX Edge—New HyperFlex Edge deployments can be configured with Replication Factor (RF)3 for higher resiliency and availability. RF3 is the default setting for 3 & 4 node Edge clusters and follows Cisco's best practices for production clusters.

- Compatibility Catalog—This new capability simplifies the introduction of new drives by allowing customers to perform an HX drive catalog-only upgrade to start consuming new drives and models introduced in the future, without requiring a HyperFlex Data Platform upgrade. Please note that you may need to update a separate UCS drive catalog update as well.

- Secure Admin Shell—HX 4.5(1a) introduces a new command-line shell, the Admin Shell, which restricts commands executable by an authenticated “admin” user login to a set of allow-listed administrative commands. Command-line login to the Controller VM as the “root” user is also removed. The Admin Shell improves the built-in security posture of the Controller VM by reducing its attack surface. An advance shell for troubleshooting can be requested from within the Admin Shell, which requires a Cisco Consent Token from Cisco TAC, and should only be used with guidance by Cisco TAC.

- HX Hardware Acceleration Card Support with Native Replication—HX 4.5.(1a) enables support for HX Hardware Acceleration cards (PID: HX-PCIE-OFFLOAD-1) with Native Replication pairing between a source and target cluster to provide DR capabilities. Both the source and the target HyperFlex clusters must have HX Hardware Acceleration enabled and should be on the HX 4.5.(1a) release.

Intersight-Powered Features

- N:1 Replication for HyperFlex Edge Clusters—Provides the ability for HyperFlex Edge clusters to take snapshots of Virtual Machines and restore using Intersight. Users can configure multiple HyperFlex Edge clusters at different sites with backup policies to create snapshots of virtual machine data which is replicated to a centralized HyperFlex backup target cluster. The VM snapshots are retained locally on the Edge cluster and a backup target cluster. These VMs snapshots are critical tools in the event that you need to recover from logical corruption, accidental deletion of data, a cluster or site outage, or planned VM migration from one edge cluster to another. For more information, see N:1 Replication for Cisco HyperFlex Edge Clusters.

- External Witness—Introducing new external witness support for HyperFlex Edge 2-Node Clusters. This feature increases cluster availability and flexibility for remote sites. For more information, see Configuring Device Connector.

Guidelines and Limitations

Upgrade Guidelines

The following list is a highlight of critical criteria for performing an upgrade of your HyperFlex system.

- Prerequisites for Upgrading HyperFlex Software

Prerequisites for Upgrading HyperFlex Software

The following tasks should be performed prior to beginning the upgrade process:

Important

Using VMware Update Manager (VUM) or VMware Lifecycle Manager (vLCM) for upgrading the ESXi on HyperFlex node is not supported. Using these upgrade methods may delete Cisco custom drivers and cause cluster outages. We recommend using Cisco Intersight or HyperFlex Connect for ESXi upgrades including the security patches from VMware or manually installing patches using the offline zip bundle with ESXCLI commands.

- Ensure Storage I/O Control (SIOC) is completely disabled on each HyperFlex datastore and the local datastore on each ESXi host in the HyperFlex cluster. This can be confirmed through the vCenter Web Client:

Datastores -> <datastore name> -> Configure -> General -> Datastore Capabilities -> Storage I/O Control -> Verify > both Status and Statistics Collection is set to Disabled.

Note

Please refer to the VMware documentation site for more details and steps to disable SIOC.

- HXDP Release 4.5 supports ESXi version 6.5 U3 and later only. If your current ESXi version is earlier than 6.5 U3, make sure to perform a combined upgrade of HXDP and ESXi to a target level 6.5 U3 or later.

- Review the Cisco HyperFlex Upgrade Guidelines in the Recommended Cisco HyperFlex HX Data Platform Software Releases - for Cisco HyperFlex HX-Series Systems.

- vCenter version check: Verify that the vCenter is version 6.5 U3 or later and meets the minimum requirements for the ESXi version being upgraded to. See, VMware Product Interoperability Matrices to ensure compatibility between vCenter and ESXi.

- Ensure all VM network port groups exist on all nodes in the cluster for vMotion compatibility.

- Ensure that the management and storage data VLANs are configured on the top-of-rack network switches to ensure uninterrupted connectivity during planned fabric failover.

- If using jumbo frames in your environment, ensure jumbo frames are enabled on the vMotion and data networks on the top of rack switch.

- Verify that the ESXi hosts are not in lockdown mode for the duration of the upgrade. Lockdown mode can be re-enabled after the upgrade is complete.

- Upgrading the VM compatibility version or hardware version of the Storage Controller Virtual Machine (SCVM) is not supported and should not be performed. This action is detrimental to the SCVM and will require a rebuild of the SCVM if performed.

- If you are using HX CSI then contact TAC.

When the cross data-center replication link bandwidth varies from value set by the customer in the HX UI pane for replication during pairing, Springpath controllers would not auto-tune the rate of transmission. This would lead to missing heartbeats and failure to replicate the data across the cluster. We would see replication failures at the UI layer. In addition, in low bandwidth and high latency network, large number of failures would occur due to non-adaptive nature of the replication rate. This enhancement would support varying link bandwidth and a bandwidth drop in link of up to 50% of configured replication bandwidth in HX by automatically controlling rate of transmission.

This defect tracks the condition where bank or rank level ADDDC/VLS Sparing copy causes a temporary stall of HX Controller VM on the impacted node to trigger one or more of the following failure symptoms:

1. If the impacted node had the Zookeeper Leader process running, it can potentially terminate multiple Zookeeper sessions leading to storfs restarts on multiple nodes and eventually an APD

2. The stalling may cause Zookeeper client running on the impacted node to timeout and the session could expire leading to storfs process on that node to restart. This will result in a temporary unhealthy event.

3. The stalling may cause storfs process to observe a high IO latency on one or more drives with active IO requests pending on those drives. This could lead to drives being marked as block listed and the cluster would become unhealthy until the drives are auto-repaired.

- Hypercheck Health Check Utility— Cisco recommends running this proactive health check utility on your HyperFlex cluster prior to upgrade. These checks provide early visibility into any areas that may need attention and help ensure a seamless upgrade experience. For more information, see the HyperFlexHealth & Pre-Upgrade Check Tool TechNote for full instructions on how to install and run Hypercheck.

- Expanding existing M4 cluster with M5 converged nodes is supported.

- Expanding existing M5 cluster with M4 converged nodes is not supported.

- Expanding existing mixed M4/M5 cluster with M4 or M5 converged nodes is supported.

- Adding any supported compute-only nodes is permitted with all M4, M5, and mixed M4/M5 clusters using the HX Data Platform 2.6 or later Installer. Some example combinations are listed here, many other combinations are possible.

Example combinations:
Expand mixed M4/M5 cluster with compute-only B200, C220, C240 M4/M5
Expand M4 cluster with compute-only B200 M5, C220 M5, C240M5

- Only expansion workflow is supported to create a mixed cluster. Initial cluster creation with mixed M4/M5 servers is not supported.

- All M5 servers must match the form factor (220/240), type (Hybrid/AF), security capability (Non-SED only) & disk configuration (QTY, capacity, and non-SED) of the existing M4 servers. For more information on drive compatibility, refer to the Cisco Hyperflex Drive Compatibility document.

- HX220-M5 will use a maximum of 6 capacity disks (2 disk slots to remain empty) when mixed with HX220-M4.

- HX Edge, SED, LFF, Hyper-V, and Stretched Clusters do not support mixed M4/M5 clusters.
