New IBM ServeRAID M5014 and M5015 Controllers

ServeRAID M5014 and M5015 SAS/SATA Controllers from IBM offer a cost-effective enterprise-grade RAID solution for internal HDDs and integrate emerging SAS technology into an organization’s storage infrastructure. At 6 Gbps, the M5014 and M5015 offer improved performance over their predecessors.

Ideal for supporting server mission-critical applications where high levels of sustained read and write operations are required, such as video streaming, Web content, video-on-demand, security and surveillance, fixed content, and reference data storage, the M5014 and M5015 offer RAID 0, 1, 5, 10, and 50. In addition, they are capable of Online Capacity Expansion (OCE), Online RAID Level Migration (RLM), single controller multipathing, load balancing, and other key RAID data protection features. M5014 comes with 256 MB of DDR2 SDRAM and supports an optional ServeRAID M5000 Series Battery Kit and M5015 comes with 512 MB of DDR2 SDRAM and an intelligent battery backup module. This memory attaches directly to the adapters, providing the performance demanded by today’s enterprise client, and is x8 lane PCI Gen 2 compliant.

ServeRAID M5014 and M5015 SAS/SATA Controllers support SAS and SATA hard drive redundant configurations for server storage, thereby providing investment protection. The M5014 and M5015 can be configured and managed with MegaRAID Storage Manager (MSM) and MegaCLI (Command Line Interface) tools.

The ServeRAID M5014 and M5015 SAS/SATA Controllers are covered under IBM warranty. These adapters carry a one-year limited warranty or, when installed in a System x server, assume your system’s base warranty and any IBM ServicePac upgrade.

ServeRAID M5000 Series Battery Kit
The kit provides an enterprise-grade battery for added performance on high-density servers that require battery-backed protection.

It adds a cost-effective enterprise-grade intelligent battery backup solution to an organization’s storage infrastructure. With 48 hours of data retention time while on battery backup, data is guaranteed to be safe during an emergency. The kit offers the performance advantages of DRAM as a write cache medium.

ServeRAID M5000 Series Battery Kit uses a battery ‘gas gauge‘ to accurately estimate the remaining energy capacity of the battery, similar to the way a cell phone or laptop computer does. In addition, it offers a monthly learn cycle where write caching for the system is turned off so that the battery can be discharged and recharged in order to recalibrate the gauge.
