When one of the hard drives in a RAID group fails and an idle or standby drive immediately replaces the failed hard drive, this drive is known as a “hot spare”. The “hot spare” hard drive doesn’t store any data when it’s idle. It can be a global hot spare or a dedicated hot spare in a specific RAID group. When one of disks fails in a RAID group, the hot spare disk will replace […]

Local Backup: “Local” means local device, it could possibly be a hard drive, desktop, and server or NAS that connects to an external device. In a sense, it’s like a DAS, external hard drive, external CD/DVD writer, tape drives, or other solid state storage, e.g. flash memory, thumb drive, CF card, SD cards […]

What is giant frame / giant packets（Jumbo Frame）? Jumbo Frame is a feature that is supported on the NIC and hub; it’s specifically designed for Gigabit Ethernet industry standard, a long packet format. With Jumbo Frame, you can get Gigabit effectiveness of Ethernet network, allowing data transfer effectively of 50%-100%.

Introduction HA stands for High Availability and was at first a computer design approach.  Then it evolved into a more complex paradigm and a Linux-based solution. We’ll talk about both of those aspects. Everything started with the urging needs of more and more available for applications: banking, science, cloud computing, e-mail, gaming and so one. The goal is to get as close as possible from 100% available, which means 0 interruption of service since the […]
