What is dell EMC VPLEX?

What is dell EMC VPLEX?

The Dell EMC VPLEX is a network-based, virtualized storage product designed to create high-availability storage between datacenters and to provide the ability to move applications and data between storage environments. VPLEX leverages Dell EMC’s common hardware design employed in the Unity, VNX, and PowerMax/VMAX.

How VPLEX works?

VPLEX uses an in-band architecture which means that data flowing between a host and a storage controller flows through one or more directors. On the front end, VPLEX presents an interface to a host which looks like a standard storage controller SCSI target.

What is the replication for Vnx?

VNX Replicator provides efficient, asynchronous data replication over IP networks, and offers the following benefits: Replicate file systems and Virtual Data Movers. Replicate to a remote system across any distance. Advanced replication scenarios like one-to-many, cascaded, and incremental attach.

How do I check my VPLEX SFP status?

Log into V Plex using service user to V Plex. CLI. List the s FPS. On all directors on V Plex to check their power levels using the command ll engines director’s hardware s FPS as indicated.

How do I create a storage view in Vplex?

1. View available storage. Go to Provision Storage select cluster > Storage Arrays.
2. Claim storage volumes. Storage volumes must be claimed before they can be used in a cluster.
3. Create extents from storage volumes.
4. Create devices from extents.

What is Vplex witness?

EMC VPLEX Metro uses a cluster guidance mechanism known as VPLEX Witness to provide continuous availability in the event of an entire site failure. Using VPLEX Witness ensures that Continuous Availability can be delivered by VPLEX Metro.

What Vplex local?

VPLEX Local brings non-disruptive data mobility to applications and virtual machines across storage arrays within the same data center. Perfect for workload balancing, or relocating due to planned infrastructure maintenance and technology refreshes, VPLEX Local accomplished all this with zero application disruption.

What is EMC VNX storage?

Dell EMC VNX is a family of enterprise-grade unified file and block storage systems. The Dell EMC VNX family of storage systems combines data storage scalability and flexibility with industry-leading simplicity and efficiency, reducing the total costs of ownership and operation of the storage system.

What is MirrorView Vnx?

EMC Mirrorview/A is an asynchronous remote replication solution for EMC VNX and Clariion storage arrays. Asynchronous replication sends data to a distant site and sends periodic updates for any changed data.

How do I create a distributed volume in VPLEX?

Instructions

1. Create a Logging Volume.
2. Identify claimed storage.
3. Create Extents from selected storage.
4. Create Local Devices.
5. Create Distributed Device.
6. Attach Rule-set / Detach Rules.
7. Create Virtual Volumes on the new Distributed Device and export to hosts.

Is Vnx a NAS or SAN?

The VNX systems provide a wide set of connectivity options for block access and for file access as a NAS system.

What is the difference between VNX and unity?

Unity is 3x faster than VNX. Reduction from 7U to 2U form-factor. Almost 50% power reduction. Significantly faster rack installation.

What are the OS for EMC storage?

Storage Array (SAN/NAS) operating systems (OS) list.

What does Dell Vnx stand for?

What is VNX? VNX stands for: V – Optimized for Virtualization.

Is Dell unity NAS or SAN?

Dell EMC Unity OE provides block LUN, VMware Virtual Volumes (VVols) and NAS file system storage access. Multiple different storage resources can reside in the same storage pool, and multiple storage pools can be configured within the same DPE/DAE array.

What is Lun in EMC storage?

The LUN is used as a logical disk identifier that enables the use of the storage (Figure 19). Figure 19: LUN Created on the New Storage Pool. Next, you must define the NFS pool to enable ESXi hosts to access the storage. To do this, follow these steps: Select the VNX system in Unisphere.

What is EMC SAN storage?

EMC provides solutions for storage area network (SAN) and network attached storage (NAS) environments. EMC FC5300, FC4500 and FC4700-2 fiber channel storage arrays provide highly available storage for a variety of workgroup, midrange and enterprise applications.

What is LUN and pool?

Pool LUNs comprise a collection of slices. A slice is a unit of capacity that is allocated from the private RAID groups to the pool LUN when it needs additional storage. Pool LUNs can be thin or thick. Thin LUNs typically have lower performance than thick LUNs because of the indirect addressing.

What is LUN provisioning?

Thin provisioning enables storage administrators to provision more storage on a LUN than is currently available on the volume. Users often do not consume all the space they request, which reduces storage efficiency if space-reserved LUNs are used.

What is difference between NAS and SAN?

Both SAN and network-attached storage (NAS) are methods of managing storage centrally and sharing that storage with multiple hosts (servers). However, NAS is Ethernet-based, while SAN can use Ethernet and Fibre Channel.

Is NFS NAS or SAN?

NFS (Network File System) is a protocol that is used to serve and share files on a network. Similar protocols include SMB (Server Message Block) and AFP (Apple Filing Protocol). In short, a NAS system can use the NFS protocol to perform its task. However, a NFS is not a NAS.

How many types of LUN are there?

LUN Types. VDS supports five LUN types: simple, spanned, striped, mirrored, and striped with parity. Simple, spanned, and striped LUNs are non-fault tolerant; mirrored and parity LUNs are fault tolerant.

What is LUN mapping?

LUN mapping is the process of controlling which hosts have access to specific logical units (LUs) within the disk controllers. LUN mapping is typically done at the storage system level. Host mapping is done at the software level.

What is the difference between thick and thin LUN?

A thick LUN differs from a thin LUN by the fact that all storage space assigned to that LUN is allocated at the time the LUN is created, rather than when it is needed. In addition, a thick LUN cannot be assigned more space than what is available in non-reserved storage.

Why SAN is faster than NAS?

SANs are the higher performers for environments that need high-speed traffic such as high transaction databases and ecommerce websites. NAS generally has lower throughput and higher latency because of its slower file system layer, but high-speed networks can make up for performance losses within NAS.
