What is ECC memory and why is it used in servers?
ECC (Error-Correcting Code) memory detects and corrects single-bit memory errors, enhancing system stability and reliability—essential in data centers.
How do you differentiate between SATA and SAS drives?
SAS drives off How do you differentiate between SATA and SAS drives?How do you differentiate between SATA and SAS drives?er faster speeds, better reliability, and dual-port access compared to SATA, which is more cost-effective for bulk storage.
What is RAID 10 and why is it used in a data center?
RAID 10 combines mirroring and striping, offering high performance and redundancy—ideal for critical applications.
Describe the POST process.
POST (Power-On Self-Test) checks hardware components during startup to ensure they function correctly before booting.
What’s the purpose of a BMC (Baseboard Management Controller)?
BMC allows remote monitoring and management of servers, including power control and hardware diagnostics.
