- Intersight support for NIC-based-HX—The 10 or 25 Gigabit Ethernet (GE) switch NIC-based topology is available for 2-, 3-, and 4-Node topologies. It provides a fully redundant design that protects against switch (if using dual or stacked switches), link and port failures. For more information see the Cisco HyperFlex Edge Deployment Guide, Release 5.0(x)

New Supported Drives

New 1.6TB NVMe cache drive is supported in HX 5.0(2b) on M5 and M6 All NVMe clusters.

HX 5.0(2b) supports the ability to handle inter-operability of mixed cache drives on HyperFlex M5 and M6 All Flash and All NVMe clusters with certain hardware configurations:

- Existing cluster with 375G cache can be expanded with 1.6TB cache.

- New cluster creation with heterogeneous cache drives needs a two-step approach for a minimum of 4 node cluster: (Step 1) cluster creation with minimum three of lesser capacity 375G cache; (Step 2) cluster expansion with 1.6TB cache. New heterogeneous cluster with less than three 375G cache is not supported. Upgrade to homogenous cluster with 1.6TB cache is recommended.

Guidelines and Limitations

Important

Do not upgrade HyperFlex Stretch clusters to HXDP 5.0(2b) See Software Advisory https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/sw/SA/sw-advisory-hyperflex-release-5-0-2b.html

- Hyper-V is supported exclusively on M5 severs.

For HX Edge M6 Support:

- OVA based installer does not support HX Edge M6. Use Intersight for lifecycle management

- HX datacenter clusters can be deployed using either OVA or Intersight installer.

- 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.

Important

Upgrades to HXDP Release 5.0(2e)- Refer to HX Field Notice and apply the mitigation before upgrading the cluster to HXDP Release 5.0(2e). Any cluster running HXDP Release 5.0(2a), 5.0(2b), 5.0(2c), or 5.0(2d) may be affected by the field notice and should apply the mitigation before upgrade to 5.0(2e) to avoid the issue. Mitigation is not required for upgrades to HXDP Release 5.0(2g) or later.

- 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.

- Clusters running HXDP Release 4.0(2x) or later can upgrade directly to 5.5(1a).

- HXDP Release 5.0 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. M6 nodes require a minimum of ESXi 6.7 U3 or later supported version.

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

- Beginning with Cisco HXDP Release 5.0(2a), full feature functionality and configuration changes require a valid Cisco HyperFlex Software License. HX Connect users with expired or insufficient licenses at the end of the evaluation or the grace period after the license compliance date, view a prominent countdown banner that alerts the user to the license compliance need and provides a link to the license renewal page until the license expiration is remedied.

In the event a license passes both the license expiration date and the grace period countdown, the current configurations will operate as expected with limited information. Renewing the license allows a user to resume full feature functionality, and make configuration changes. For details and examples of the banners, see the License Compliance and Feature Functionality section of the Cisco HyperFlex Systems Ordering and Licensing Guide.

- vCenter version check: Verify that the vCenter meets the minimum requirement 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 and SSH service is enabled and set to start and stop with the host for the duration of the upgrade. Lockdown mode can be re-enabled after the upgrade is complete along with disabling SSH service.

- Blade Package and Rack Package versions are not displayed in the Host Firmware Package: HyperFlex-m5-con and HyperFlex-m6-con for M6 nodes.

- 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.

Mixed Cluster Expansion Guidelines - Cisco HX Release 5.0(x)

General Guidelines:

- HX240c M6 is not able to use the additional slots if combined in a cluster with M5 or M4 nodes.

- HX220c M6 uses a maximum of 6 capacity disks (2 disk slots to remain empty) when mixed with HX220-M4.

- All servers must match the form factor (220/240), type (Hybrid/AF), security capability (Non-SED only) and disk configuration (QTY, capacity, and non-SED) across the cluster.

Mixed Cluster Expansion Options: Supported

- Expanding existing M4 or M5 or M4+M5 cluster with M6 converged nodes is supported.

- Expanding existing mixed M4/M5/M6 cluster with M4 or M5 or M6 converged nodes is supported.

Note

The staging of the HX 5.0(1c) and HX 5.0(2a) versions of the storfs-se-core package is in progress and will follow Cisco HXDP 5.0(2a) posting. As a result, eDelivery of the storfs-se-core package is temporarily delayed until posting is complete. When posting is complete, the eDelivery link will automatically include HX 5.0(1c) and HX 5.0(2a) versions of the storfs-se-core package. In the meantime, Customers who want to enable HX Software Encryption should make sure they have ordered the special software PID for Software Encryption (HXDP-SW-PKG-SE-K9=); refer to the HyperFlex Ordering and Licensing Guide for details.

Reminder: If you are enabling HX Software Encryption for the first time in a cluster, your storfs-se-core package must match the HXDP version of your cluster; refer to the HyperFlex Data Platform Administration Guide (Release 5.0).
