Introduction

The ServeRAID F Series family of products offers MegaRAID data protection and flexible onboard flash technology that can be used in various ways to help improve performance and server storage density. These products are optimized to deliver the performance that is demanded by the ever-growing I/O requirements of today's enterprises. They integrate popular disk media such as SAS and SATA HDDs and emerging solid-state drives into an organization's storage infrastructure by offering embedded transparent caching and data storage capabilities with the onboard flash memory.

Did you know?

The ServeRAID F Series portfolio is designed with individual flash modules onboard. These flash modules can be configured in a RAID array to support latency-sensitive data storage, including the boot volume, the golden image in a virtual desktop infrastructure (VDI) application, or storing tempdb or indexes and data objects from a database. Concurrently, they support a caching volume, dynamically identifying application hot data to be stored and serviced from the flash for improved performance and reduced latency.

Features

The ServeRAID F5115 SAS/SATA Controllers have the following standard features:

  • Auto-resume on array rebuild or array reconstruction after the loss of system power

    Auto-resume uses non-volatile RAM (NVRAM) to save the rebuild progress during a host reboot or power failure to automatically resume from the last checkpoint. Auto-resume ensures that data integrity is maintained throughout the process. The card supports a number of features that can be implemented without rebooting the server. Applications, such as email and web server, benefit from avoiding downtime during the transition.

  • Online Capacity Expansion

    Online Capacity Expansion (OCE) allows the capacity of a virtual disk to be expanded by adding physical disks or using unused space on existing disks without requiring a reboot.

  • Online RAID Level Migration

    Online RAID Level Migration, which is also known as logical drive migration, provides the ability to migrate a virtual disk from any RAID level to any other RAID level without requiring a reboot. System availability and application functionality remain unaffected.

  • Fast initialization for quick array setup

    Fast initialization quickly writes zeros to the first and last sectors of the virtual drive. This feature allows you to immediately start writing data to the virtual drive while the initialization is running in the background.

  • Consistency check for background data integrity

    The consistency check verifies that all stripes in a virtual disk with a redundant RAID level are consistent. The consistency check mirrors data when an inconsistent stripe is detected for a RAID 1 and recreates the parity from the peer disks in the case of a RAID 5 or RAID 6. Consistency checks can be scheduled to take place periodically.

  • Extensive online configuration options and advanced monitoring and event notification

    Management tools provide convenience for the configuration of logical volumes and alerting when errors occur or are about to occur.

  • Patrol read for media scanning and repairing

    Patrol read is a background sentry service designed to proactively discover and correct media defects (bad sectors) that arise normally as a disk drive ages. The service issues a series of verify commands, and if a bad block is discovered, the card's firmware uses RAID algorithms to re-create the missing data and remap the sector to a good sector. The task is interruptible based on controller activity and host operations. The firmware also provides an interface where the patrol read task can be initiated, set up for continuous operation, and terminated from a management application. Patrol read can be activated by a manual command or automatically.

  • Global and dedicated hot spare with revertible hot spare support

    A hot spare rebuilds data from all virtual disks within the disk group in which it is configured. ServeRAID provides the ability to define a physical disk as a hot spare to replace a failed drive. Hot spares can be configured as either global or dedicated. A global hot spare allows any physical drive to be designated as a hot spare. A dedicated hot spare allows the user to assign a hot spare drive to a particular array of the same drive type.

  • Single controller multipathing (failover) I/O load balancing

    The ServeRAID firmware detects and uses multiple paths from the controllers to the SAS drives that are in enclosures. With redundant paths to the same port of a device, if one path fails, another path can be used to communicate between the controller and the drive. Using multiple paths with load balancing, instead of a single path, can increase reliability through redundancy.

  • MegaRAID SafeStore support for self-encrypting drive (SED) services

    MegaRAID SafeStore encryption services offer instant secure erase and local key management for self-encrypting drives. This technology represents a significant step forward in securing data on a disk drive from any unauthorized access or modification resulting from theft, loss, or repurposing of drives. Instant secure erase permanently removes data when repurposing or decommissioning SEDs. SafeStore local key management provides the necessary management and protection of SEDs by using a simple pass phrase, security key identifier, and security key file that can be set and applied to all SEDs that are assigned to a ServeRAID adapter. This feature removes the complexity of managing each SED’s unique encryption key, and it essentially relieves the administrator of most of the daily tasks of securing data.

  • MegaRAID FastPath SSD performance acceleration

    MegaRAID FastPath software provides high-performance I/O acceleration for SSD-based virtual drives by using an extremely low latency I/O path to increase the maximum I/O per second (IOPS) capability of the controller. This feature boosts the performance of applications with a highly random data storage access pattern, such as transactional databases.

  • Intelligent caching for traditional hard drives

    Intelligent caching algorithms help identify application hot data (the frequently accessed data) that is stored and accessed from flash memory, enabling the lowest possible latency). By combining flash memory and HDDs, the solution enables the lower cost per GB at the lower cost per transaction ratios over products supporting only flash memory.

  • WebBIOS configuration utility for pre-boot array configuration and management

    WebBIOS is a utility that is built into the ServeRAID controller that allows you to configure drive groups and logical drives before installing or booting the operating system.

  • Human Interface Infrastructure (HII) utility

    The Human Interface Infrastructure (HII) configuration utility is a tool to configure controllers and physical and logical drives from the pre-boot UEFI environment.

  • MegaRAID Storage Manager management software

    MegaRAID Storage Manager is an easy-to-use advanced RAID management application that is used across the entire family of ServeRAID M and F controllers. It allows you to configure, monitor, and maintain drive groups, virtual drives, and advanced features with an intuitive GUI, reducing administrative efforts and simplifying troubleshooting.

Solid-state memory: Solid-state memory cells have an intrinsic, finite number of program/erase cycles that each cell can incur. As a result, solid-state storage has a maximum amount of program/erase cycles to which it can be subjected. Solid-state storage that reaches this limit might fail to operate according to its specifications. Writes are tracked and reported by the adapters management utility and might be affected by application writes, data patterns, and maintenance tasks that are designed to maximize data integrity.
