Nutanix Cloud Manager (NCM) offers our customers simplicity and ease of use to build and grow their cloud deployments faster and realize rapid ROI, by providing intelligent operations, self service and orchestration, visibility and governance of spend, security and teams, all through a unified Multi-cloud management solution.

NCM licenses can be purchased and applied on the number of physical CPU cores capacity in your deployment. Licenses are portable across hardware platforms and are available in 1 through 5-year term options.

By default, NCM provides coverage for all Nutanix and on-prem VMWare environments, metered per core. For supporting public cloud environments using the same NCM deployment, customers should purchase appropriate NCM Cloud SKUs as add-ons. Three public cloud-focused add-ons are available as SKUs- NCM Self-Service add-on for Public Cloud SKU, NCM Cost Governance SaaS SKU, and NCM Security Central SaaS SKU. These add-ons are metered by the number of Virtual Machines (VM) managed in the public cloud. Note: For on-prem environments, Cost Governance is available for AHV and ESXi on AOS, and Security Central is known for AHV.

NCM is also available as a fully managed Software as Service Option. Customers can experience multi-cloud self-service, app automation, governance, and security compliance capabilities, without requiring to run any on-prem Nutanix software. The NCM SaaS offering is available to purchase as à la carte SaaS licenses for these four NCM SaaS modules:

• NCM SaaS – Operations (in development) 
• NCM SaaS – Self-Service
• NCM SaaS – Cost Governance
• NCM SaaS – Security Central

NCM SaaS licenses are metered by the number of Virtual Machines (VM) managed in the public cloud.

Nutanix Cloud Infrastructure (NCI) and Nutanix Cloud Manager (NCM) can be purchased together in 3 ‘better together’ Nutanix Cloud Platform (NCP) bundles:

ICAP stands for internet content adaption protocol is an open standard being adopted to connect devices to enterprise-level virus scan engine . same way with the nutanix files is to enable communication with external servers hosting third-party anti-virus software to scan inbound data (files) in transit via Secure Proxy before sending it to the backend destination server.

ICAP WORKFLOW

The ICAP service runs on each Nutanix Files file server and can interact with more than one ICAP server in parallel to support horizontal scale-out of the antivirus server. The scale-out nature of Files and one-click optimization greatly mitigate any antivirus scanning performance overhead. If the scanning affects Nutanix Files FSVM performance, one-click optimization recommends either increasing the virtual CPU resources or scaling out the FSVMs. This feature also helps both the ICAP server and Files scale out, ensuring fast responses from the customer’s antivirus vendor

WHY Nutanix files integration with AV server is important

Ransomware is a persistent concern that requires multiple security controls and software layers to mitigate integration is important to protect users from malware and viruses,

WHAT all third-party vendor are support with Nutanix files

1. Trand Micro
2. McAfee
3. BitDefender
4. Symantec
5. sentinelone

HOW to configure integration

1. In the Files Console, go to Configuration > Antivirus.
2. Connect the ICAP server.
   1. Click + Connect ICAP Server.A new row appears for new ICAP server details.
   2. Enter the following information in the corresponding fields:
      • IP address or hostname
      • Port (the default port number is 1344)
      • Description
   3. To save the configuration, click the check mark icon.For a detected antivirus server, the software tests the validity of the configured server and updates the status to OK.
   4. Ensure the connection status automatically updates to OK.
   5. Click Next.

AOS integrates storage, compute and networking resources into a scalable, secure, resilient and easy-to-use software-defined infrastructure.

AOS 6.0 has various new features and notably enables advanced disaster recovery capabilities for organizations of all sizes and expands workload support for leading big data and analytics applications. Additionally, has other workload acceleration and enterprise grade features, such as resiliency improvements to gain insights and control over the self-healing process and ability to reserve capacity.

Please review the release notes before deploying AOS 6.0

Here is a sample of the latest features:

Disaster Recovery

• Near-Sync Autonomous Schedules: Native near-zero always-on data loss solution for applications running on Nutanix HCI. Available with Protection Domain
• DR Dashboard: Provides global visibility into DR landscape with LEAP. Gives team one place to monitor and manage their ability to keep business operations functional in the face of disaster. Brings observability to DR for meeting/maintaining RPO SLAs, Recovery Readiness and DR Reports
• DR Traffic Encryption: Encrypt DR traffic across WAN links without the need for dedicated encryption hardware or VPN.Native SSL based encryption is now integrated with Nutanix AOS, enabling secure replication even where VPN tunnels are unavailable. Available with Protection Domain
• DR Replication Performance: DR Replication Performance: Next gen architecture for data mobility across clouds with improved performance and tight SLAs
• Instant Restore for AHV: Instantly recover the workload even though the disk data for the workload are not locally available in the underlying AOS cluster. Migrate the disk data back to (seed) the AOS cluster without interruption to the recovered workload

Core Data Path

• Option to reserve rebuild(spare) capacity for a cluster: The Reserve Rebuild Capacity feature simplifies cluster resiliency management by allowing you to reserve storage capacity required to recover and rebuild from failures. AOS calculates, reserves, and dynamically manages capacity required for self-healing after a failure.
• Rebuild progress indicator and ETA: The new Rebuild progress indicator in Prism enables administrators to better manage cluster resiliency by providing additional insight into the self-healing process such as the rate of progress, expected time of completion and other details for rebuild operations
• Brownfield AES: Provides ability to convert existing pre-AES containers to AES
• Support mix storage capacity for HW Swap: This feature adds support mixing storage drive capacity for drive RMA and node capacity increase use-cases.
• Improve performance (e.g.: metadata re-warming) after failures/CVM restart/change of vdisk host: This feature helps mitigate potential application performance impact during certain CVM restarts or live migrations by proactively pre-filling the metadata cache

AHV

• P2P intra cluster VM live migration: While VM live migration is in progress if the migrate task restarts, VMs can be left in a paused state or killed in certain scenarios causing downtime, this feature overcomes these issues
• ADS vGPU Support: We now have Acropolis Dynamic Scheduling (ADS) support for VMs with virtual GPUs (vGPUs)
• Nvidia vGPU Console Support: Provide GPU support for our VM console (Also part of 5.20)
• Scale out PE Lazan: With this feature, cluster state capture phase is distributed among every Lazan slave to make it faster and more scalable. Each slave then sends the captured state to Lazan master making anomaly detection faster and the CPU usage to compute the cluster state is also distributed among the nodes.
• PC UI using v3 APIs: The goal was to upgrade the APIs used for VM operations for our Prism UI, while preserving the existing feature set and workflows

Jumbo Frame is basically a ability to increase packet payload size which can be beneficial when processing a large amount of data through the network itself.

Nutanix AHV uses the standard Ethernet max transmission unit (MTU) of 1,500 bytes for all external communication by default. Jumbo frames are optional, because the standard 1,500 byte MTU still delivers excellent performance, but increasing the MTU can be beneficial in some scenarios

Default MTU vaule is 1500

Jubmo Frame MTU Vault is 9000

Nutanix recommanded to use Jubmo frame to use for Nutanix Volume to represent high Performance ISCSI Storage External Server which can help to increase Effciency for application such as oracle database connected to the Nutanix volumes .

Be sure to plan carefully before enabling jumbo frames. Configure the entire network infrastructure from end to end with jumbo frames to avoid packet fragmentation, poor performance, or disrupted connectivity.

Check the current configuratin :-

root@ahv# ovs-appctl bond/show

root@ahv# ip link | grep mtu

Reconfigure CVM to make changes :-

nutanix@cvm$ sudo ip link set eth0 mtu 9000 
nutanix@cvm$ sudo ip link set eth2 mtu 9000

To permanently modify the MTU so it persists through a restart, append the string ‘MTU=”9000“’ to the end of the following configuration files on the CVM:

nutanix@cvm$ sudo echo ‘MTU=“9000”’ >> /etc/sysconfig/network-scripts/ifcfg-eth0 
nutanix@cvm$ sudo echo ‘MTU=“9000”’ >>  /etc/sysconfig/network-scripts/ifcfg-eth2

host reboot is required hence follow the safe reboot task.
