What is Vserver in netapp?
What is Vserver in netapp?
A virtual storage server (Vserver) contains data volumes and one or more LIFs through which it serves data to the clients. Starting with clustered Data ONTAP 8.1. 1, a Vserver can either contain one or more FlexVol volumes, or a single Infinite Volume. In a cluster, Vserver facilitates data access.
What is the command to check Vserver?
To determine the available languages, enter “vserver show -language? ” at the clustershell command prompt and at the Vserver prompt. If this parameter is specified, the command displays information only about the Vserver or Vservers that have the specified Snapshot policy.
How do I create a Vserver?
Creating a Vserver by using the vserver create command
- The cluster must have at least one non-root aggregate created by using the aggr create command.
- You must have at least 1 GB of space on the aggregate for the Vserver root volume.
What are three types of Vservers?
Types of Vservers
- Admin Vserver.
- Node Vserver.
- Data Vserver.
What is Flex volume in NetApp?
A FlexVol volume is a data container associated with a Storage Virtual Machine (SVM) with FlexVol volumes. It gets its storage from a single associated aggregate, which it might share with other FlexVol volumes or Infinite Volumes. It can be used to contain files in a NAS environment, or LUNs in a SAN environment.
What is RAID DP in NetApp?
RAID-DP is the default RAID type for all aggregates. RAID-DP provides double-parity disk protection when the following conditions occur: There is a double-disk failure within a RAID group. There is a single-disk failure or a media error on the disk, or both instances within a RAID group.
What is SVM storage?
Storage Virtual Machines (SVMs, formerly known as Vservers) contain data volumes and one or more LIFs through which they serve data to the clients. SVMs securely isolate the shared virtualized data storage and network, and each SVM appears as a single dedicated server to the clients.
What is a LUN in NetApp?
A LUN is a logical representaion of storage. It looks like a hard disk to the client. It looks like a file inside of a volume. You can see the Data ONTAP ‘Block Access Management Guide for iSCSI and FC’ for documentation.
What is the difference between RAID 6 and RAID-DP?
The advantage of RAID-DP compared to regular RAID6 is that growing your RAID set is just a matter of adding drives, whereas with RAID6 you’d have to re-distribute all the data over the newly grown RAID, which takes ages, is error-prone and makes performance suffer.
What is SVM?
Storage Virtual Machines (SVMs, formerly known as Vservers) contain data volumes and one or more LIFs through which they serve data to the clients. In a cluster, SVMs facilitate data access. A cluster must have at least one SVM to serve data. SVMs use the storage and network resources of the cluster.
What is SVM in Linux?
SVM is short for Statechart Virtual Machine, a fully functional interpreter for UML statecharts. SCC (StateChart Compiler) generates efficient Java source code from statechart descriptions.
What are NetApp aggregates?
An aggregate is a collection of disks (or partitions) arranged into one or more RAID groups. It is the most basic storage object within ONTAP and is required to allow for the provisioning of space for connected hosts.
What is a Virtual Storage Server (VServer)?
A virtual storage server (Vserver)contains data volumes and one or more LIFs through which it serves data to the clients. Starting with clustered Data ONTAP 8.1.1, a Vserver can either contain one or more FlexVol volumes, or a single Infinite Volume.
What is Linux-VServer technology?
The Linux-VServer technology is a soft partitioning concept based on Security Contextswhich permits the creation of many independent Virtual Private Servers(VPS) that run simultaneously on a single physical server at full speed, efficiently sharing hardware resources.
What is the VServer root volume used for?
The Vserver root volume does not contain any of the configuration information of the Vserver. Optionally, the Vserver root volume can also contain user data. However, it is best not to store user data in the root volume. When you create a Vserver, it is started automatically and is in running state.
How do I create a vserver in a cluster?
Creating a Vserver by using the vserver create command. You can either create a Vserver with FlexVol volumes or a Vserver with Infinite Volume to serve data to the clients by using the vserver create command. A cluster can have one or more Vservers with FlexVol volumes and Vservers with Infinite Volumes.
