Glossary

silent installation A command line interface to install the Host Agent, Navisphere Server Utility, Navisphere Storage System Initialization Utility, or Navisphere CLI on all attached Windows servers. You create a response file on one of the attached servers, which stores the setup configuration that allows you to install these applications on all remaining attached servers by using one command. This command requires no user input.

silent removal A command line interface to remove the Host Agent, Navisphere Server Utility, Navisphere Storage System Initialization Utility, or Navisphere CLI on all attached Windows servers. You create a response file on one of the attached servers, which stores the setup configuration that allows you to remove these applications on all remaining attached servers by using one command. This command requires no user input.

SP See storage processor (SP).

SP log (of A time-ordered list of messages about storage-system events (such as storage-systemerrors) maintained by the SP. You can view this log using Navisphere

events) Manager.

SP memory modules Memory modules (SIMMs or DIMMs) that provide the local storage for an SP. An SP must have at least two 4-Mbyte memory modules to support the storage-system cache.

SPS See standby power supply (SPS).

standby power supply A unit that provides backup power for a Fibre Channel storage (SPS) system with SPs in case of a power outage. An SPS is required for the

storage-system write caching. If power fails, the SPS allows the SP to write the cache image to the cache vault area on disk. You can replace an SPS under power, without interrupting applications.

Storage group A group of LUNs on a storage system with the Access Logix option. A storage system can have multiple storage groups. A storage group can be connected to multiple servers, but a server can be connected to only one storage group in each storage system.

storage processor (SP) A printed-circuit board with memory modules that control the disks in the storage-system chassis. The SP runs FLARE software that controls the operation of the storage system. For higher availability, a site can use a second SP in a storage-system chassis.

CLARiiON specifications

EMC CLARiiON is a storied name in the realm of data storage solutions, renowned for its reliability, scalability, and advanced features. As a part of EMC's pioneering approach to enterprise storage, CLARiiON systems are designed to meet the demands of businesses ranging from small enterprises to large data centers.

One of the standout features of EMC CLARiiON is its support for both Fibre Channel and iSCSI protocols, which allows for versatile deployment options in various network environments. This dual-protocol capability is key in enabling organizations to leverage existing network infrastructures while providing the flexibility to scale as needed.

The architecture of CLARiiON is built on a modular design, featuring a series of storage processors, also known as storage controllers. This design not only enhances performance but also allows for easy upgrades and expansions. The use of RAID (Redundant Array of Independent Disks) technology ensures data redundancy and integrity, offering a variety of RAID levels to cater to specific performance and data protection needs.

EMC CLARiiON also integrates advanced data management features such as online capacity expansion, which enables administrators to add drives without disrupting operations. This is complemented by the system's support for thin provisioning, which allows for more efficient use of storage space, presenting only the amount of storage that is actually being used.

One notable technology employed by CLARiiON is the Storage Resource Management (SRM) suite, which provides powerful tools for monitoring, reporting, and managing storage usage and performance. This suite enables IT teams to optimize their storage investments by identifying trends and potential issues before they affect service levels.

Another critical aspect is the inclusion of automatic load balancing features, which help distribute workloads evenly across available storage resources. This promotes optimal performance and reduces the risk of bottlenecks during peak usage times. Additionally, the snapshot technology embedded in CLARiiON offers users the ability to create point-in-time copies of data, facilitating rapid recovery in the event of data loss or corruption.

Lastly, EMC CLARiiON systems are designed with high availability in mind. They often feature redundant components and advanced failover capabilities to ensure seamless operations. With these characteristics, EMC CLARiiON stands as a robust solution for organizations seeking to enhance their data storage strategy, driven by cutting-edge technology and tailored to meet diverse business requirements.
