Patented page-based volume management enables automatic movement of data while it is in use. This technology provides the foundation for online expansion, automatic configuration and load balancing, performance optimization, and advanced software functionalities - all with continuous access to data. That means no downtime for increasing capacity, moving data between storage tiers, or load balancing storage, and most management tasks are handled by the array, not the administrator.
As a result, the EqualLogic PS Series of arrays makes enterprise-class shared-block storage practical for all servers and applications. With its unique peer storage architecture, the PS Series delivers high performance and availability in a flexible environment with low cost of ownership.
Whether you are seeking to consolidate storage, migrate from DAS or NAS, streamline data protection, or expand capacity, the PS Series of proven, self-managing storage arrays will meet the demanding requirements of your business-critical environment. In this context, peer describes the collaboration and equal partnership of a single, simple architecture; components and arrays function as peers, working together to share resources, evenly distribute loads, and collaborate to help optimize application performance and provide comprehensive data protection.
The result is an intelligent storage array that can deliver rapid installation, simple management, and seamless expansion. Using patented, page-based data mover technology, members in a storage area network SAN work together to automatically manage data, load balance across resources, and expand to meet growing storage needs. Because of this shared architecture, enterprises can use PS Series arrays as modular building blocks for simple SAN expansion see Figure 1.
Figure 1. Grouping multiple Dell EqualLogic PS Series arrays helps increase capacity and performance linearly—without increasing management complexity This architecture provides the basis for numerous features and capabilities, including peer deployment, control, provisioning, protection, and integration. Peer deployment is a SAN configuration technology that can sense network topology, automatically build RAID sets, and conduct a system health check to help ensure that components are fully functional.
Peer deployment enables IT staff to potentially install, configure, and deploy most EqualLogic arrays in minutes. Peer control offers virtualized storage management with a single view. PS Series arrays are designed to be self-managing; systems are designed to continuously monitor storage resources and automatically load balance data across controllers, network connections, and disk drives to help deliver optimal performance.
Peer control automates key functions for configuration, management, storage pooling, and data distribution, helping minimize the complexity of storage administration. Peer provisioning enables administrators to dynamically provision resources to meet application requirements—including not only disk space, but also connectivity, security, performance, and data protection.
When application requirements change, the storage configuration can change seamlessly. Peer provisioning is designed to simplify expansion while systems remain online; new arrays can be automatically added to the group and automatically connect to the SAN. Expansion is linear, enabling administrators to scale not only disk drives but also controllers, ports, cache, and performance as the environment grows.
Peer provisioning enables enterprises to purchase storage on demand, which facilitates efficient use of both capital and storage resources. Advanced thin provisioning capabilities are included, giving administrators additional flexibility in providing storage to applications. Administrators can also allocate virtual storage to volumes up to preset limits and add physical capacity on demand.
In both physical and virtual server environments, cloned volumes can be rapidly assigned to different servers to help meet changing needs. Peer protection starts with a robust design that avoids single points of failure and is designed to provide greater than It also includes built-in features such as application-aware snapshots for quick recovery and remote replication for disaster protection.
These features enable administrators to quickly create end-to-end solutions that can help provide comprehensive protection against multiple types of failure or outage. Peer integration provides a comprehensive software toolkit to facilitate the deployment, ongoing management, and protection of EqualLogic SANs in Microsoft Windows OS environments and VMware environments.
The EqualLogic peer storage architecture makes enterprise-class performance, scalability, and reliability possible in an intelligent, automated management framework that helps eliminate tedious administrative tasks while enabling easy best-practices storage management. Peer deployment: Rapid installation EqualLogic PS Series arrays can be fully functional within minutes of opening the shipping box. Built into the array is an automatic sensing and configuration technology that helps eliminate complex and cumbersome manual tasks, enabling a quick start.
Once it identifies the network topology, this intelligence checks component functionality and automatically builds RAID sets. With a few simple steps and without special expertise, administrators can deploy an enterprise-class SAN seamlessly, without downtime.
This capability helps eliminate the complex manual configuration of other SANs, allowing administrators to focus on servers and applications. Peer control: Cost-effective enterprise data services The PS Series has built-in storage features once relegated solely to top-tier data centers, enabling enterprise-class storage for virtually every size organization.
Built-in monitoring and notifications provide e-mail, syslog support, and comprehensive Simple Network Management Protocol SNMP monitoring and traps—all standard features. Snapshots can be used for quick recovery and offloading backup operations. PS Series arrays are designed to implement safe snapshot recovery in which data is not discarded unintentionally, helping provide the flexibility to implement true enterprise storage. Automatic load balancing The EqualLogic approach to optimizing performance is simple: maximize the horsepower of all available components in the SAN.
Because of the unique peer storage architecture used by EqualLogic PS Series arrays, instead of relying solely on individual components to deliver high performance, peer control leverages all relevant components.
It automatically load balances to seamlessly spread data across active storage resources, helping maximize performance by intelligently optimizing the available network connections, cache, controllers, and drives. Through this optimization, each PS Series array can support high transactional workloads and database applications.
When multiple arrays are added together the PS Series quickly scales, and performance grows linearly with each additional array. Tiering and pooling The EqualLogic tiering capability enables administrators to prioritize applications within a SAN by placing them on separate storage resources, each optimally configured for the required service level of the application.
Administrators can configure separate storage pools within a single SAN to help build an efficient, flexible, easy-to-manage storage environment. Using this "SAN within a SAN," administrators can gain the advantages of consolidation, but can also easily separate workloads as needed: by application, service level, disk type, cost, or even by department within the organization.
For example, large, high-density SATA PS Series arrays can be placed in dedicated pools to provide capacity-oriented tiers of storage for files, near-line applications, archiving, and de-duplicated backups. Because online data movement is built into all PS Series arrays, administrators can adjust application resources and move data between different pools of storage without downtime or disruption.
This centralized event and performance monitoring, historical reporting tool can assist with operational planning, trend analysis, and troubleshooting. Flexible viewing options range from high-level group summaries to sophisticated analyses, including detailed statistics on performance, latency, capacity, volumes, and network activity. In addition, both pre-defined and customized views let administrators select their preferred method of accessing information. Peer provisioning: Self-managing, scalable storage The intelligence of peer provisioning combined with the modular design of PS Series arrays enables administrators to quickly and easily expand storage capacity without affecting data availability.
They can start with a single storage array—then, when storage, performance, and network requirements grow, they can add more arrays to the group to scale the environment with more capacity, performance, and network bandwidth automatically. While scaling guidelines may vary by model, administrators can combine any EqualLogic arrays together in the same SAN. Configuring one or more EqualLogic PS Series arrays as a PS group enables administrators to manage the arrays as a single system with a shared pool of storage.
EqualLogic peer provisioning automates the key functions needed to configure, manage, and scale storage, helping eliminate much of the complexity of storage administration.
Each group member is automatically configured and participates in balancing the load, distributing data, and tracking host access to data, without requiring user intervention—helping keep storage management simple, regardless of scale. The power of peer provisioning also enables a key feature: on-demand growth. Because capacity expansion in PS Series arrays is non-disruptive, administrators can add storage resources while applications remain online.
As a result, you can purchase only the storage you need, when you need it - helping to prevent both underutilization and over provisioning and avoiding future downtime. With a PS Series SAN, enterprises can purchase the storage capacity they need today, and plan for future storage growth knowing that when they need to expand, they can do so easily and without taking the system offline.
Thin provisioning is an important advanced feature of peer provisioning that enables the automatic addition of physical capacity on demand up to preset limits. Advanced thin provisioning helps make buy-as-you grow storage management and virtualization seamless for servers and applications. When administrators create a volume, they can size it for the long-term needs of the application without initially allocating the full amount of physical storage.
Instead, as the application needs additional storage, capacity is allocated to the volume from a free pool. The EqualLogic implementation of thin provisioning provides enhanced flexibility and safety controls—with proactive, user-defined threshold alarms and controls, administrators can depend on automatic space allocation without worrying about reaching allocation limits or unexpected depletion of physical storage.
Peer provisioning can offer significant economic benefits to enterprises of all sizes, because they can purchase physical storage when they actually need it. These benefits include increased asset utilization, reduced management costs, reduced floor space footprint, reduced power and cooling costs, and smart, efficient capital expenditures. Comprehensive system monitoring EqualLogic system monitoring capabilities are designed to provide administrators with a comprehensive view of the health and status of their SANs.
SAN HQ provides centralized event and performance monitoring, historical reporting, capacity trending, and detailed analyses for groups, pools, and individual volumes.
In addition, within the EqualLogic Group Manager, administrators can view the status of individual SAN components such as drives, power supplies, and controllers, as well as the overall system.
Combined with automatic sparing and spare utilization, this feature helps enhance protection and ensure optimal disk performance. E-mail home To help ensure the availability of systems and data, PS Series arrays come standard with group event notification methods e-mail, syslog, and SNMP , but also allow administrators to enable e-mail home functionality. E-mail home can automatically contact EqualLogic customer support if a hardware component such as a disk, control module, fan tray, or power supply fails, or if the firmware on a PS Series array is updated.
E-mail home functionality enables EqualLogic to rapidly respond to issues and assist administrators. Auto-replication offers the advantages of geographic isolation—a critical component in any true disaster recovery plan—without the traditional complexity.
Administrators can quickly and easily configure volumes for replication, letting the PS Series arrays manage the underlying hardware resource complexity. A catalog of recovery points is maintained at each disaster recovery site, providing multiple points of recovery from which to choose in the event of a disaster—a choice that helps protect against "cascading" failures such as software viruses.
Making a disaster recovery site operational is simple, even if the primary site already stores terabytes of data. EqualLogic PS Series arrays enable administrators to perform an initial manual sync by copying primary site data to transportable media, physically shipping the media to the remote site, unloading the data, and then starting up the automatic replication.
