Lenovo ThinkServer RAID 720i 2GB Transportable Flash Module and Supercapacitor Upgrade 4XB0F28697

ThinkServer always meets the demand on performance enhancement and feature enablement by continuous improvement on products and options.

Upgrading your systems with the new options will bring you great values with flexibility, scalability, field-proven reliability.

2GB/4GB Modular flash and Supercapacitor

The features that are added when a cache upgrade is installed are as follows:

• Support for RAID 6 and 60

  RAID 6 and 60 provide additional protection compared to RAID 5 and 50 by implementing a double-parity configuration.

• MegaRAID flash cache protection

  MegaRAID flash cache protection uses NAND flash memory, which is powered by a supercapacitor, to protect data that is stored in the controller cache. This module eliminates the need for a lithium-ion battery, which is commonly used to protect DRAM cache memory on PCI RAID controllers. To avoid the possibility of data loss or corruption during a power or server failure, flash cache protection technology transfers the contents of the DRAM cache to NAND flash using power from the offload power module. After the power is restored to the RAID controller, the content of the NAND flash is transferred back to the DRAM, which is flushed to disk.

• MegaRAID CacheCade Pro 2.0 SSD caching for traditional hard disk drives

  MegaRAID CacheCade 2.0 read/write software accelerates the performance of hard disk drive (HDD) arrays with only an incremental investment in solid-state drive (SSD) technology. The software enables SSDs to be configured as a dedicated pool of controller cache to help maximize the I/O performance for transaction-intensive applications, such as databases and web serving. CacheCade software tracks data storage access patterns and identifies the most frequently accessed data. The hot data is then automatically stored on the solid-state storage devices that are assigned as a dedicated cache pool. CacheCade requires a cache optoin with flash backup.

• 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 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.
