Let us get a Brief look into each RAID Levels. RAID are managed using mdadm package in most of the Linux distributions. Here we will see only the RAID Levels which is used mostly in real environment. By defining chunk size we can increase the I/O performance. Chunks are just a size of data which can be minimum from 4KB and more.If any one of the drive failed in our array this hot spare drive will be used and rebuild automatically. Hot spare is just a spare drive in our server which can automatically replace the failed drives.In RAID 1 it will save the same content to the other disk too. Mirroring is used in RAID 1 and RAID 10.

If we use 3 disks half of our data will be in each disks.

This won’t have full data in a single disk.

Stripe is sharing data randomly to multiple disk.

Parity method in raid regenerate the lost content from parity saved information’s.

Hardware RAID Card will look like below: Hardware RAID Featured Concepts of RAID Very costly investments needed for a large scale. Stores cache while rebuild even if there is power-failure, it will store the cache using battery power backups. They have NVRAM for cache to read and write. They are dedicated RAID Controller which is Physically built using PCI express cards. I have tried replacing them with tp-link and now BrosTrend Wi-Fi.Hardware RAID have high performance. I had some WiFi repeaters that worked really well, however they burned out over time because of the environment. Here is my scenario I have production devices that need a static IP address.

WiFi to Ethernet Bridge that allows Static clients? Networking.

They want new hosts, and cloud is a hard-stop for them so it's not up for discu. Have a client with two old Hyper-V hosts, no clustering/HA/failover/etc configured, with 6 vms between them and 5tb of company data on old host 1 > DC/Fileserver as drive E.

Best practice for 2x VMWare host HA/failover, and storing 5tb+ of company data? Virtualization.

Tolkien's 'The Hobbit' is published by George Allen and Unwin in LondonWhen the first edition of The Hobbit: or, There And Back Again was first published - 85 years ago, on Sept.

Currently they are logged in as a general user and then create a helpdesk ticket. We have engineers that are running programs, installing, changing, developing and need to be able to utilize elevated command prompts.

How do you handle users needing local Admin password Security.

Http:/ / / articles/ linuxsoftwareraid.html This web page is remarkable because it also provides a nice cross-reference to other diagnostic and monitoring tools.

The utilities include sg variants for the traditional dd command, tools for scanning and mapping the SCSI bus, tools for issuing low-level SCSI commands, tools for timing and testing, and some example source & miscellany.

#Raid monitor linux driver

This driver supports modern SATA and USB-connected disks, as well as SCSI, FCP, SAS disks.

The sg3_utils package provides a set of utilities for use with the Linux SCSI Generic (sg) device driver. The package contains low level utilities including sgdskfl to load disk firmware, sgmode to get and set mode pages, sgdefects to read defect lists, and sgdiag to perform format and other test functions.

Other efforts have been made to enable various common hardware RAID adapters and their drivers on Linux." The project is slightly misnamed: the Linux scsi layer handles all modern SATA drives, as well as FCP, SAS and USB drives, and thus is applicable to most all modern hardware.

"This project includes changes that enhance the Reliability, Availability and Serviceability (RAS) of the drivers that are commonly used in a Linux software RAID-1 configuration. These tools can report a variety of disk drive health statistics, and the smartd daemon can run continuously to log events into the syslog. The smartmontools package provides a set of utilities for working with the Self-Monitoring, Analysis and Reporting Technology (SMART) system built into modern IDE/ATA/PATA, SATA and SCSI-3 disks. In this case, you might find the following useful: Alternately, some rescue operations require low-level configuration tools. Sooner or later you will feel the need for tools to diagnose hardware problems, or simply monitor the hardware health.
