Description
Product Overview of the Smart Array P220I Controller
HP 659331-001 Smart Array P220I Controller is a hardware component that provides RAID (Redundant Array of Inexpensive Disks) functionality to HP ProLiant servers. It is an essential component for data storage and retrieval in enterprise-level computing systems. This device comes with 512MB Flash Back Write Cache that enhances the performance and reliability of the RAID system. In this article, we will discuss the features and benefits of this controller in detail.
Features
The HP Smart Array P220I Controller is designed to support SAS (Serial Attached SCSI) and SATA (Serial Advanced Technology Attachment) hard drives with a data transfer rate of up to 6 Gb/s. It supports RAID levels 0, 1, 10, 5, and 50, which allows for data redundancy and improved data access times. This controller comes with 512MB Flash Back Write Cache, which is a type of cache memory that temporarily stores write data to the disk. This helps to improve the performance of the RAID system as it reduces the amount of time it takes to write data to the disk.
The HP Smart Array P220I Controller also supports hot-plug hard drives, which means that you can add or remove hard drives from the system without turning it off. This feature makes it easy to replace a faulty hard drive without disrupting the operation of the system. The controller also supports online capacity expansion and RAID level migration, which means that you can add more hard drives to the system or change the RAID level without losing any data.
Benefits
The HP Smart Array P220I Controller comes with 512MB Flash Back Write Cache, which helps to improve the performance of the RAID system. This is because the cache memory temporarily stores write data to the disk, which reduces the amount of time it takes to write data to the disk. This results in improved system performance, which is especially important in enterprise-level computing systems where data access times are critical.
Data Redundancy
The HP Smart Array P220I Controller supports RAID levels 0, 1, 10, 5, and 50. RAID is a data storage technology that combines multiple hard drives into a single logical unit for the purpose of data redundancy, improved data access times, or both. RAID 1, for example, duplicates data across two hard drives, which means that if one drive fails, the data is still accessible from the other drive. This helps to improve data availability and reduce the risk of data loss.
Hot-plug Hard Drives
The HP Smart Array P220I Controller supports hot-plug hard drives, which means that you can add or remove hard drives from the system without turning it off. This feature makes it easy to replace a faulty hard drive without disrupting the operation of the system. It also allows you to add more hard drives to the system without shutting it down, which reduces downtime and improves system availability.
Online Capacity Expansion
The HP Smart Array P220I Controller supports online capacity expansion, which means that you can add more hard drives to the system without losing any data. This is a useful feature for enterprises that need to increase their storage capacity over time. With online capacity expansion, you can add more hard drives to the system without shutting it down or losing any data, which helps to improve system availability and reduce downtime.
RAID Level Migration
The HP Smart Array P220I Controller also supports RAID level migration, which means that you can change the RAID level without losing any data. This is a useful feature for enterprises that need to change their storage configuration over time. For example, if you initially set up your system with RAID 0 for performance reasons, but later decide that you need data redundancy, you can migrate to RAID 1 or RAID 5 without losing any data
