According to Nutanix Support & Insights1, “When you create a lifecycle policy for a bucket, you can choose whether to apply it only to new objects that are added after creating the policy or also apply it retroactively to existing objects.” Therefore, if this option is not selected, then existing data will not be moved by the tiering rule.

Task Step Step 1 Step 2 step 3 Step 4 Select Log onto a file server VM via SSH Change the password Respond to the prompts, providing the current and new Nutanix user password Repeat the steps on the remaining FSVMs

According to Nutanix Files :- Exports and Shares Basics1, “A distributed share is an SMB share or NFS export that can be hosted by multiple FSVMs. A distributed share can handle more concurrent sessions than a standard share.” Therefore, the administrator should create six distributed shares for each department to access its own shared namespace and handle 3,000 concurrent sessions.

According to Nutanix Support & Insights1, a distributed share is a type of SMB share that distributes the hosting of top-level directories across FSVMs. To access a distributed share, you need to use a DNS name that resolves to all FSVMs in the cluster.

If some DNS records are missing or incorrect, then some FSVMs may not be reachable by their DNS name, resulting in the network object not found error. This could explain why data located on FSVM 3 can be accessed, but data located on FSVMs 1 and 2 is inaccessible.

Nutanix Files can automatically rebalance data across FSVMs to optimize performance and capacity utilization. You can also manually trigger a rebalance from the Files Console Dashboard tab by clicking on Apply Recommendation.https://next.nutanix.com/community-blog-154/nutanix-files-4-0-new-features-performance-improvements-40544

S3 stands for simple storage service and it is a widely used object storage protocol that allows you to store and retrieve any amount of data from anywhere on the web. SMBv2 stands for server message block version 2and it is a file sharing protocol that enables access to files on remote servers. Nutanix Unified Storage Objects supports both S3 and SMBv2 protocols for data access.

According to the Nutanix Unified Storage (NCP-US) v6 documentation, once WORM (Write-Once-Read-Many) has been enabled on an Objects bucket, versioning cannot be immediately enabled. Instead, the WORM configuration must be disabled and then re-enabled, this time with Enable Version and Enable WORM checked. Since the administrator did not select Enable Version during the initial configuration, this step is necessary in order to enable versioning.

You can disable WORM within 24 hours of enabling it on a bucket1. This will allow you to change the versioning settings on the bucket.

Object storage is a good fit for applications that require versioning, replication, and a write-once-read-many (WORM) access model. Since eCommerce sites often store a large amount of unstructured data such as images, videos, and other multimedia content, object storage can provide a scalable, cost-effective, and highly available solution.

Object storage is also a good fit for Kubernetes-based applications that use microservices architecture, as objects can be accessed from multiple pods at the same time, without the need for complex file system sharing. Additionally, object storage can be easily integrated with Kubernetes using operators or API calls.

On the other hand, while volumes and file storage solutions such as SMB and NFS can also store static content, they may not be the best fit for the given application requirements. Volumes are often limited in terms of scalability and replication, while file storage solutions may not provide the same level of versioning and WORM capabilities as object storage.

As a result, the best solution for the given application requirements is Object storage.

Note that the exact implementation and configuration of the object storage solution may vary based on factors such as performance, availability, and security requirements.

This is because this bundle contains LCM file manager component that is required for LCM inventory to work in dark site mode.

• Download lcm_file_analytics_x.x.x.tar.gz bundle from Nutanix portal which contains File Analytics software binaries.
• Download lcm_file_manager_x.x.x.tar.gz bundle from Nutanix portal which contains LCM file manager component that handles file operations such as upload, download and delete.
• Transfer both bundles to a dark site web server that is accessible by LCM.
• Configure LCM settings in Prism Element to use dark site mode and specify the URL of the dark site web server.
• Perform LCM inventory which scans for available software bundles on the dark site web server.
• Upgrade File Analytics using LCM which downloads and installs File Analytics software binaries from lcm_file_analytics_x.x.x.tar.gz bundle.

According to the Nutanix Files SMB Migration Guide1, Nutanix Files supports SMB protocol V2 and V31. SMB is a native protocol for Nutanix Files that allows file sharing between Windows clients and servers1.

Connect with MPIO to the iSCSI Data Services IP. The iSCSI Data Services IP (DSIP) is a virtual IP address that provides load balancing and failover for iSCSI traffic across all CVMs in a cluster. The MPIO (Multi-Path I/O) option enables multiple paths for iSCSI traffic between Windows clients and Nutanix Volumes. The Cluster Virtual IP (CVIP) is used for management and communication between CVMs and should not be used for iSCSI traffic.

According to File Auditing and Analytics for your Nutanix Files Enterprise Cloud1, File Analytics is a feature that captures real-time user audit data and file metadata for Nutanix Files environments. It allows you to create custom reports based on various criteria such as file type, size, owner, access time, etc.

According to Nutanix Files 3.8 and File Analytics 3.0 | Nutanix Community2, File Analytics allows you to add new file categories based on custom file extensions such as .zyx or .zzz. You can then use File Distribution View to see a collapsed view of space usage, number of files, and changes within a given time frame for each file category.

Therefore, if the administrator needs to analyze data created by a custom application that uses custom-built file extensions such as .zyx or .zzz, they can add a new file category in File Analytics and use File Distribution View to provide the required information.

IP addresses of all FSVMs should be entered. FSVMs are File Server Virtual Machines that provide iSCSI services for Nutanix Volumes. The iSCSI initiator in Windows client devices should be configured with the IP addresses of all FSVMs in a cluster to enable load balancing and failover. The Enable multi-path option should be checked to use multiple paths for iSCSI traffic. The Nutanix MPIO drivers are not required for Windows clients as they can use native MPIO drivers.

According to Encryption-Files | Nutanix Community1, SMB3 message encryption is a feature that encrypts messages on the file server side and decrypts them on the client side. However, clients that do not support encryption (Linux, Mac, windows 7) cannot access a share with encryption enabled.

According to Nutanix Support & Insights2, Nutanix Files supports SMB3 encryption for SMB3 client-server traffic. This means that only clients that support SMB3 protocol can access encrypted shares.

Therefore, if the users are accessing the shares from Linux desktops, they will not be able to access them because Linux does not support SMB3 encryption.

 Nutanix volume groups are collections of vDisks that can be exposed to virtual machines or physical hosts using iSCSI protocol. Nutanix volume groups have a shared attribute that allows multiple VMs to access them concurrently.

In the step for attach the volume group to the RAC VMs, he must create it with an attribute of shared = true. This is because if the volume group is not created with shared = true, then only one VM can access it at a time, which would prevent Oracle RAC from working properly.

To support a new RF3 container, the effective capacity of the Nutanix cluster must be at least three times the size of the data that needs to be stored on it3. This is because RF3 means that each data block is replicated three times across different nodes or blocks for fault tolerance3.

This is because if you have 4 TiB of effective capacity with RF2 (which means each data block is replicated twice), then you need 9 TiB of effective capacity with RF3 (which means each data block is replicated three times).

Nutanix Files is a file storage service that supports SMB and NFS protocols. Access Based Enumeration (ABE) is a Windows feature that filters the list of available files and folders on the file server to include only those that the requesting user can access. Nutanix Files also supports replication to a DR site using Async DR.
