EonStor A04U-G2421 series is a disk array system that supports SATA-II hard disk. It provides a single array with 4 SATA-II (300MB/sec) hard disks in a 1U Rackmount streamlined space and provides the advanced NCQ (Native Command Queuing) technology to improve overall performance. It also provides backward compatibility. Through conversion, you can connect your existing PATA or SATA-I hard disk. It provides an Ultra 320 SCSI channel connection on the host and supports a wide range of hosts and operating systems, such as SUN Solaris v8/9, Windows NT/2000/2003 Server, Redhat Linux, SuSe Linux, etc. No driver software is required to easily connect. For applications such as surveillance systems, SOHO environments, and connecting small servers, this series offers an excellent price/performance ratio and is a good choice.
The EonStor A04U-G2421 is a 1U rack‑mount storage array that supports up to four SATA‑II 3.5" drives (max 4 TB) and offers a range of RAID levels for data protection. It features a 64‑bit PowerPC 400 MHz CPU, dual PCI‑X bus with hardware XOR, and up to 2 GB/s system bandwidth.
Management can be performed via RS‑232 terminal mode, Java‑based RAIDWatch, web interface, SNMP, email, fax, or SMS alerts, providing flexible remote monitoring and control for surveillance, SOHO, or small‑server environments. This manual is written in Chinese.
