The Symmetrix VMAX system is an innovative platform built around a scalable Virtual Matrix

design and solely built for virtual environment . The Symmetrix VMAX series includes the

Symmetrix VMAX and the Symmetrix VMAX SE models, and meets a wide range of high-end

requirements for scalability, performance, and cost.

The Symmetrix VMAX is ideal for high-end configurations that require performance and the

scaling capability to start as small as one engine pair and 96 drives, and grow to a maximum of

eight engines and 2,400 drives. Symmetrix VMAX’s incremental scalability allows to meet your

growth requirements by adding VMAX engines and disk drives non-disruptively to the existing

frame. It provides support for Fibre Channel, iSCSI, Gigabit Ethernet, and FICON connected

hosts. Front-end and back-end connectivity supports up to 128 host ports and 128 disk channels.

The VMAX also leverages 2.3 Gigahertz multi-core processors. The new Virtual Matrix

provides the interconnect that enables resources to be shared across all V-Max engines to enable

massive scale out.

Enginuity is the operating environment for Symmetrix VMAX and provide simplified storage

management and provisioning, as well as additional replication, migration and volume

configuration option. Symmetrix VMAX provide local replication and remote replication

through EMC TimeFinder and EMC SRDF (Symmetrix Remote Data Facility).




The Symmetrix VMAX system bay houses all the system components which include:

•VMAX Engines – Provide up to eight VMAX Engines within a system bay on standardconfiguration.

•Matrix Interface Board Enclosure – Contains a Virtual matrix interface board that connects the

VMAX engines and also contains two power supply/cooling modules.

•Standby power supply (SPS) module – Two SPS modules for each VMAX Engine provide

backup power in the event of an power interruption.

•Service Processor – Provides local, remote or optional modem connection to the Symmetrix

system, as well a keyboard, video and mouse interface. Service Processor components download

the Symmetrix system configuration to the directors in the VMAX Engines and also providediagnostic and maintenance utilities for the Symmetrix system.

A Storage Bay consists of either eight or sixteen Drive Enclosures, and eight SPS modules.

Symmetrix V-Max arrays are configured with capacities of up to 120 disk drives for a half

populated bay or 240 disk drives for a full populated bay. Each Drive Enclosure includes the

following components: redundant power and cooling modules for disk drives, two Link Control

Cards, and 5 to 15 disk drives.




Each VMAX Engine includes four quad-core Intel Xeon processors, 64-128 GB of Global

Memory, 8-16 ports for front-end host access or Symmetrix Remote Data Facility channels

using Fibre Channel, FICON, or Gigabit Ethernet. It also has 16 back-end ports connecting to up

to 360 storage devices using 4Gb Fibre Channel, SATA, or Enterprise Flash Drives. Each

VMAX Engine has its own redundant power supplies, cooling fans, SPS Modules, and

Environmental Modules. Each VMAX engine includes two redundant director modules

providing parallel access and replicated copies of all critical data. Symmetrix VMAX array

combines Front End, Back End, and Memory into a single Director, reducing cost and increasing

performance.

The Virtual Matrix Architecture replaces individual, function-specific directors with Symmetrix

VMAX Engines, each containing a portion of Global Memory and two directors capable ofmanaging Front End, Back End, and remote connections simultaneously. The slide reviews the

Virtual Matrix architecture in more detail. The system starts with a VMAX Engine as a high-

availability base configuration. The VMAX Engine is connected to the Virtual Matrix and

allows all system resources — including CPU, memory, drives, and host ports — to be

dynamically accessed and shared by any application. Additional VMAX engines are added

nondisruptively to efficiently scale system resources. The Virtual Matrix supports a total of eight

VMAX engines in a single system. As shown, the new architecture enables significant increases

in scalability. Scalability has improved in all aspects: Front End connectivity, Global Memory,

Back End connectivity, and usable capacity. The Virtual Matrix is redundant and dual active and

supports all Global Memory references, all messaging, and all management operations includinginternal discovery and initialization, path management, load balancing, fail over, and fault

isolation within the array.




A disk is sliced into Hyper or disk slices and protection schemes are then incorporated, creating

the Symmetrix volume. Symmetrix logical volumes are defined by using the service processor

and SymmWin interface. Configuration changes can be performed online using the EMC

ControlCenter Configuration Manager and Solutions Enabler Command Line Interface.




A host views a Symmetrix Logical Volume in the same manner as it sees any other disk device.

The host is unaware of how the volume is configured in the Symmetrix, its protection scheme,

or any other special attributes. Hosts assign disk device logical device names that vary

depending on the operating system.

Symmetrix Management Console is used by Symmetrix for device management for both the

Symmetrix VMAX and Symmetrix DMX products. There are several key features introduced to

simplify storage management in virtual data centers and cluster environments. As data centers

continue to embrace virtualization, management tools are required to tier, consolidate, and scale

physical resources.

Symmetrix Management Console manages the following features:

Auto-provisioning Groups — Map and mask Initiator Groups, Storage Ports, and Storage

Groups

Virtual Provisioning — Also known as thin provisioning

Enhanced Virtual LUN technology — Data mobility within the array and movement between

tiers FAST (Fully Automated Storage Tiering)

Symmetrix Optimizer automatically tunes, monitors, analyzes, and migrates logical volumes to

maintain optimal performance, with no disruptions to applications or users. Symmetrix

Optimizer’s load-balancing automation technology analyzes volume activity to identify hot and

cold logical volumes for swaps; this automates the time consuming task of balancing the load on

the Symmetrix back end. The tedious task of disk-performance tuning is completely automated.
