Description
Product Overview of the IBM 43W4297
The IBM 43W4297 ServeRAID MR10i is a RAID controller designed for server systems. The controller provides advanced data protection and performance features for enterprise-level storage environments. It is designed to work with SAS and SATA hard disk drives and Solid State Drives (SSDs), allowing you to create various RAID configurations to meet your specific storage requirements. In this article, we’ll take a closer look at the IBM 43W4297 ServeRAID MR10i Storage Controller and its key features and benefits.
Key Features of ServeRAID MR10i Storage Controller
The IBM 43W4297 ServeRAID MR10i Storage Controller supports several RAID levels, including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and RAID 50. RAID stands for Redundant Array of Independent Disks, which is a data storage technology that combines multiple physical disks into a single logical unit for data redundancy, performance improvement, or both.
Cache Memory
The IBM 43W4297 ServeRAID MR10i Storage Controller features 256MB of cache memory. Cache memory is a type of volatile memory that stores frequently accessed data for faster access. The cache memory on the MR10i controller helps improve performance by reducing disk access times.
SAS/SATA Interface
The IBM 43W4297 ServeRAID MR10i Storage Controller supports both SAS and SATA interfaces, which allow you to connect both SAS and SATA hard disk drives and SSDs to the controller. SAS and SATA are two different types of disk drive interfaces, with SAS being faster and more reliable than SATA.
Battery Backup Unit (BBU)
The IBM 43W4297 ServeRAID MR10i Storage Controller comes with a battery backup unit (BBU) that provides power to the cache memory in the event of a power failure. This ensures that data in the cache memory is not lost due to sudden power outages.
Online Capacity Expansion (OCE)
The IBM 43W4297 ServeRAID MR10i Storage Controller supports Online Capacity Expansion (OCE), which allows you to add new hard disk drives to an existing RAID configuration without the need to take the system offline. This feature is particularly useful for expanding the storage capacity of your server without interrupting business operations.
Online RAID Level Migration (ORLM)
The IBM 43W4297 ServeRAID MR10i Storage Controller also supports Online RAID Level Migration (ORLM), which allows you to migrate from one RAID level to another without taking the system offline. This feature is useful when you need to change the RAID level to meet changing business requirements or to improve performance.
RAID Level Migration
The IBM 43W4297 ServeRAID MR10i Storage Controller also supports RAID Level Migration, which allows you to migrate from a lower RAID level to a higher RAID level. This feature is useful when you need to improve data protection or performance by upgrading your RAID configuration.
