Lenovo ThinkSystem RAID 530 Series Internal RAID Adapters

Product Guide

The ThinkSystem RAID 530 family are entry-level 12 Gb SAS/SATA internal RAID adapters that offer a cost-effective RAID solution for small to medium business customers. These cacheless adapters support RAID levels 0/1/10/5/50, and include an extensive list of RAS and management features.

The family is comprised of two adapter types:

The ThinkSystem RAID 530-4i supports up to four internal SAS and SATA drives The ThinkSystem RAID 530-8i supports up to eight internal SAS and SATA drives

The ThinkSystem RAID 530-8i is shown in the following figure.

Did you know?

Along with an extensive list of enterprise RAID capabilities, the RAID 530 Series adapters offer advanced drive diagnostic technologies. In the event of a physical drive failure, the drive is placed in a shielded state and the controller starts drive diagnostics to determine if the drive is indeed failed or can be restored. This saves time, money and server downtime associated with transient drive failures and unnecessary drive replacement.

Technical specifications

The ThinkSystem RAID 530 Series internal RAID adapters have the following specifications:

PCIe 3.0 x8 host interface

12 Gbps SAS/SATA RAID controllers, based on the Broadcom MegaRAID 9440 adapter family

Cacheless (not upgradeable)

Connectivity for up to 4, or 8 internal SAS or SATA drives

Support for intermixing SAS and SATA HDDs and SSDs. Mixing SAS and SATA drives in the same array is not supported. Mixing of HDDs and SSDs in the same array is not supported.

Support for intermixing of 12 Gbps and 6 Gbps drives.

Support for RAID 0, 1, 10, 5, and 50 standard (The 530-4i supports only RAID 0, 1 in the SN550 and RAID 0, 1, 10, 5 in the SN850 because those blade servers only support two and four drives respectively)

† The 530-4i adapter for use in the SN550 blade server only supports RAID 0 and RAID 1 because the server has only two drives. The 530-4i adpater for use in the SN850 blade server only supports RAID 0, 1, 5 and 10 because the server has only four drives. * The only technical difference between 7Y37A01082 and 4Y37A16225 is the included cables.

Features

The ThinkSystem RAID 530 adapters have the following standard features:

MegaRAID FastPath SSD performance acceleration

MegaRAID FastPath software provides high-performance I/O acceleration for SSD-based virtual drives by using a 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.

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 new physical disks or making use of unused space on existing disks, without requiring a reboot.

Online RAID Level Migration

Online RAID Level Migration (RLM), which is also known as logical drive migration, can 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

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 RAID 1 and re-creates the parity from the peer disks for 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 have occurred or are about to occur.

Patrol read for media scanning and repairing

Patrol read is a background sentry service that pro-actively discovers and corrects 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.
