Data Avoidance

Data Avoidance technologies typically contribute the most to data efficiency because they prevent the creation of unnecessary data, which also minimizes the need for more resource-demanding data reduction technologies. With fewer back-end operations, more resources are available for front-end (user-driven) operations and applications. As Nutanix enables its built-in data avoidance technologies automatically, there is no need for manual configuration or fine-tuning.Thin ProvisioningThin Provisioning is a simple and broadly adopted technology for increasing data capacity utilization by overcommitting resources. Nutanix enables this feature in all containers by default. In deployments using the VMware ESXi hypervisor, containers are presented to hosts as natively thin-provisioned NFS datastores. Although it is a widely accepted method for increasing capacity utilization, thin provisioning traditionally has been associated with reduced storage performance. However, on Nutanix, thin provisi

Firewall Requirements

Use these firewall requirements to configure rules in your external firewall to allow Nutanix Remote Support, Pulse, SMTP, 1-click upgrades, and LCM updates. Source Controller VM / Prism Central IP addresses Destination nsc01.nutanix.net and nsc02.nutanix.net Protocol - Port TCP - 80 and 8443 Action ALLOW   Source Controller VM / Prism Central IP addresses Allows Pulse messages from the cluster to Nutanix support servers. Each Controller VM in your cluster collects Pulse configuration data continuously and sends Pulse metric data every 15 minutes to insights.nutanix.com over port 443 once every 15 minutes over HTTPS. Ports 80 and 8443 are the default ports that the cluster uses to connect to the Nutanix support servers nsc01.nutanix.net and nsc02.nutanix.net. Nutanix recommends that you open both ports. If one port is disabled, the cluster automatically tries to connect on the other. You can open the por

Updating directory Services and Authentication - Files

To update the directory services configuration, do the following:Procedure: Go to the File Server dashboard, click the File Server tab, select the target file server and then click Protocol Management Click Directory Services In the Directory Services window, select the protocols you want to use and complete the fields for the selected protocols. You can select SMB, NFS or both. Each protocol contains more fields to complete.      4.  When all the fields are correct, click the Update button. Authentication:Depending on the primary and secondary protocols configured for your file server, access and authentication configuration vary. File servers using SMB protocol must configure Active Directory (AD). File servers using the NFS protocol can use Lightweight Directory Access Protocol (LDAP), AD, or unmanaged authentication services. LDAPWhen you configure LDAP as the authentication service, Files uses Netgroups to control client access. The Files LDAP setup is based on the RFC 2307 st

Encryption-Files

Files supports AOS software encryption and in-flight message encryption for SMB3 shares.You can only apply AOS software encryption to files by activating it through Prism. Refer to the file release Notes to ensure that you are running a compatible version of AOS. SMB3 Message Encryption: After enabling message encryption, the file encrypts messages on the file server side and decrypts them on the client side (only on the new connections for the share). Clients that do not support encryption (Linux, Mac, windows 7) cannot access a share with encryption enabled. Authentication: Active Directory with Kerberos provides secure authentication. File supports the following Kerberos encryption types. Advanced Encryption Standard 128 with the Keyed-Hash Message Authentication code and Cryptographic Hash Function SHA1  Advanced Encryption Standard 256 with the Keyed-Hash Message Authentication  Message Authentication code and Cryptographic Hash function SHA1 (AES-256-HMAC-SHA1) Rivet cipher

Your guide to the Upgrades

 Most of our customers upgrade their infrastructure once every couple of months and this guide helps our customers understand  how to upgrade and what to expect from the process. In older versions of AOS, upgrades were done using “one click” or “upgrade software”. With LCM available in newer versions, the upgrades are much simpler and straightforward. Here’s the documentation  to understand pre-requisites of LCM and how LCM works:https://portal.nutanix.com/page/documents/details?targetId=Life-Cycle-Manager-Guide-v20:Life-Cycle-Manager-Guide-v20 The LCM works on one-node at a time and if the upgrade proceeds to the next node if the scheduled node is successful in upgrading to the target version. The LCM upgrade tasks can be monitored from “LCM” in Prism UI. There is essentially no downtime required for the user VMs during the upgrades.  With regards to concerns about performance, it’s always best to schedule maintenance window for the upgrades, especially with the cluster with 1G NIC ca
