Hello everyone! This time I come to talk about a project that I have been working on for a few months. If you remember some time ago I wrote about the AsBuildReport tool specifically the module to document VMware vSphere based infrastructures see the post here . Well today I come to show you a module that I help to develop with the purpose of documenting NetApp storage devices specifically on the ONTAP operating system. ...
Hello everyone, Today I will be talking a bit about how to install and configure the Ontap Mediator application that is used as an alternate way to validate the health status of a cluster collection. To set up the role of this application I will use as reference the NetApp portal documentation: ONTAP Mediator provides an alternate health path to the peer cluster, with the intercluster LIFs providing the other health path. With the Mediator’s health information, clusters can differentiate between intercluster LIF failure and site failure. When the site goes down, Mediator passes on the health information to the peer cluster on demand, facilitating the peer cluster to fail over. With the Mediator-provided information and the intercluster LIF health check information, ONTAP determines whether to perform an auto failover, if it is failover incapable, continue or stop. ...
The vSphere 7.0 U2 release provides the ability to use native snapshot when using the NFS protocol as the access mechanism. As described on the VMware blog: NFS Improvements NFS required a clone to be created first for a newly created VM and the subsequent ones could be offloaded to the array. With the release of vSphere 7.0 U2, we have enabled NFS array snapshots of full, non-cloned VMs to not use redo logs but instead use the snapshot technology of the NFS array in order to provide better snapshot performance. The improvement here will remove the requirement/limitation of creating a clone and enables the first snapshot also to be offloaded to the array. ...
Starting In Ontap 9.8 release NetApp decided to add support for the Windows SMB protocol to the FlexCache technology. At last….. In this blog, I will create a source volume as origin and a flexcache volume on a remote cluster. In the lab example I will also validate the benefit offered by the ability to extend a central CIFS share natively. I used the NetApp documentation as a reference to define what a Flexcache volume is and what it is used for. ...
Previously in a post I explained how to set up an encrypted volume using an encryption key manager (KMS) specifically from the company HyTrust . In this specific case each volume is encrypted individually using independent keys. A disadvantage of this method is that it affects the possibility of increasing the efficiency levels of data reduction such as compression, compaction and deduplication (cross-volume-dedupe). To eliminate this disadvantage the NetApp gurus came up with the idea of applying the encryption feature at the aggregate level by allowing volumes residing within the same aggregate to share the encryption key. This technology is known as NetApp Aggregate Encryption (NAE)`. This allows customers the option to take advantage of storage efficiency technologies in conjunction with the encryption process. ...
Using NetApp documentation as a reference: NetApp Volume Encryption (NVE) is a software-based technology for encrypting data at rest one volume at a time. An encryption key that can only be accessed by the storage system ensures that the data on the volume cannot be read if the underlying device is reused, returned, lost or stolen. NetApp Documentation In this tutorial I explain how easy it is to configure and manage this impressive security feature. ...
I recently posted about a how to install and configure Minio S3 on a Linux server Link Here: Minio in Centos 8 . Well in this video I show you how to configure Minio as a Scale-Out Backup Repository with VEEAM Backup & Replication v11. Really awesome VEEAM feature! Hasta Luego Amigos!
Recently in a post on the NetApp forum a user asked for help to create a function in Powershell using the DataOntap libraries. Here I show you how we use these libraries to join multiple objects with information related to the LUNs assigned in NetApp. A curious fact about this request is that natively Ontap libraries do not allow you to filter the required information and that it can be displayed in a single table. For this we create an object within PowerShell where we can build the format of the information and that this has a more logical sense. ...
