Two directors that support front-end, back-end and SRDF connections. What Are Features Of V-max? One to eight V-Max Engines 16 directors. Up to 1 TB GB usable global mirrored memory. Virtual Matrix architecture connects and shares resources across director pairs, providing massive scalability.
An intuitive, browser-based family of products that provides management of the overall storage environment, including multi vendor storage reporting, monitoring, configuration, and control. Simplifies provisioning of configurations with a large number of hosts by allowing the creation of initiator, port and storage groups. Auto-provisioning Groups is especially helpful in large, virtualized server environments that require the availability of many volumes to many host initiators and many storage ports.

New Management Integration features free up host resources and simplify Symmetrix system management by allowing you quesfions Fully Automated Storage Tiering FAST — Reduces cost for performance, saves energy, and simplifies storage tier management by allowing the dynamic allocation of data across storage questionss, based on user defined policies and on the changing performance requirements of the applications.
Provides the ability to non disruptively change disk and protection type of a logical volume, and allows the migration of open systems, mainframe, and Qusetions i volumes to unallocated storage, or to existing volume. Improves capacity utilization by allowing the allocation of more storage to than is physically consumed by a host at onset, and is allocated, as needed, from a shared pool.
Allows users to nondisruptively balance workloads and extend thin pool capacity, in small increments if required, while maximizing performance and reducing total cost of ownership.
Yes, each session holds the different configuration change locks. Up to four concurrent configuration change sessions are allowed to run at the same time, when they are non-conflicting. This means that multiple parallel configuration change sessions can run at the same time as long as the changes do not include any conflicts on Device back-end port, Device front-end clriion and on Device.
Eliminates of searching for required storage on arrays. Eliminates the host interruptions. Eliminates the storage reclamation. Initiators can be dynamically added or quetsions from initiator groups. Ports can be dynamically added or removed from port groups.
EMC Clariion (SAN) Interview Questions
Storage can be dynamically added or removed from storage groups. Only Fibre and Gig-E ports on front end directors allowed. Initiator can belongs to only one Initiator Group. Maximum of 32 Initiators contains one initiator group. Initiator groups can be cascaded. Reduce the amount of allocated but unused physical storage. Avoid over allocation of physical storage to applications. Reduces energy consumption and footprint. Provision independently of physical storage infrastructure.
Minimize the challenges of growth and expansion. Saves costs by simplifying procedures to add new storage.
Reduces disk contention and enhances performance. Maximize return on investment. Symconfigure -sid “SymID” -cmd “add dev 10E4: The number of pools that can be configured in a Symmetrix array is As many as data devices can be member of a thin pool, however the limit to the number of thin and data devices that can be configured within a Symmetrix system is 64, Only data devices may be placed in a thin pool.

The data devices must all have the same emulation. The data devices must all have the same protection type. It is recommended that data devices in a pool all reside on drives that have the same rotational speed. The data devices in the pool interviww generally be spread across as many DAs and drives of a given speed as possible.
The devices should be evenly spread across the DAs and drives.
The wide striping provided by Virtual Intervjew will spread thin devices evenly across the data devices. The storage administrator must ensure that the data devices are ekc spread across the back end. It is recommended that all data devices in a pool are of the same size. Using different size devices could result in uneven data distribution. The data device sizes should be as large as possible to minimize the number of devices required to encompass the desired overall pool capacity.
Optimizes performance by monitoring access patterns on storage arrays and transparently moving data between storage tiers. Storage provisioning with symaccess allows you to create a group of devices, a group of director ports, a group of host initiators, and with one command, associate them in what is called a masking view.
Once a masking view exists, devices, ports, and initiators can be easily added or removed from their respective groups. The steps for creating a masking view are: FAST is Symmetrix software that runs background algorithms continuously analyze the utilization busy rate of the Symmetrix array devices. The objective of tiered storage is to minimize the cost of storage by putting the right data, on the right Symmetrix tier, at clariiln right time. Ims, Db2 And Ispf. Emc Clarkion Practice Tests.
Up to GB global memory. The primary interface for managing Symmetrix arrays. Clariipn library of commands that are entered from a command line or from a script.
