The Lenovo 4Y37A09728 is a RAID adapter designed for ThinkSystem servers that need both speed and strong data protection. It connects through a PCIe 4.0 x8 slot and drives eight internal SAS ports at up to 12 Gb per second, so large databases, virtual machines, and file servers can move data quickly without becoming a bottleneck.
To guard against unexpected power loss, the card holds a 4 GB flash-backed cache. Any writes still in the queue are preserved, then completed safely when power returns. This added layer of protection helps administrators avoid lengthy rebuilds or data recovery procedures.
Flexible RAID options cover nearly every workload. Choose RAID 0 for raw performance, RAID 1 or 5 for balanced speed and redundancy, or RAID 6, 10, 50, and 60 when uptime is critical. JBOD mode is on hand if an application prefers to manage drives directly.
Deployment is straightforward in Windows Server, popular Linux distributions, or VMware ESXi. Once installed, the adapter appears in standard management tools, making it easy to create arrays, monitor drive health, and schedule cache backups.
This card is a practical upgrade for administrators who want more throughput than onboard controllers can provide, yet still need consistent protection for business-critical data. It is also RoHS compliant and comes with a Lenovo one-year limited warranty, giving you confidence that it will support your infrastructure reliably.
