LENOVO szerver RAID - ThinkSystem RAID 530-8i PCIe 12Gb Adapter

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.

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.

The following table provides the ordering part numbers for the adapters.

The following figure shows the ThinkSystem SD530 HW RAID adapter.

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)
• Support for JBOD (non-RAID) drive state
• Support for up to 64 virtual disks, up to 128 arrays, up to 16 virtual disks per array
• Support for logical drive sizes greater than 2 TB.
• Fixed 64 KB stripe size
• Supports 512e, 512n and 4K sector formatted drives
• Compliant with Disk Data Format (DDF) configuration on disk (CoD).
• S.M.A.R.T. support.

  • XClarity Administrator Configuration Patterns
  • StorCLI command-line interface
  • LSI Storage Authority (LSA) GUI interface
  • UEFI Human Interface Infrastructure (HII)

Note: CacheCade is not supported by these adapters

The following table compares the specifications of the RAID 530 internal adapters.

† 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.
