Netgear SC101

Last updated

The SC101 was a home computer networking storage product manufactured and distributed by Netgear under the Storage Central brand from around 2005 through 2010. The devices shared data stored on one or two internal disks via Ethernet links.

Description

The two models in the Storage Central line were the Netgear SC101 and SC101T.

The original SC101 model could hold one or two disks (sold separately) using Parallel ATA (known as "IDE" at the time) and had a 100 Mbit/sec Ethernet over twisted pair interface. [1]

The later Netgear SC101T model could hold one or two Serial ATA disks and had a Gigabit Ethernet interface. [2]

The ZSAN technology was licensed in 2005 from Zetera Corporation. [3]

Reviews praised the low price and ease of installation, but noted limited software support and passive cooling. [4] [5]

At least one reviewer encountered an incompatible disk drive. [6]

By January 2010 the Storage Central series was replaced by Netgear storage products using the ReadyNAS name. [7]

Software

The SC101 provided a block-level storage area network (SAN) interface, as opposed to file-level network-attached storage (NAS). Thus, like any SAN device, specific drivers and software must be installed on any client PC wishing to access the device. Only the Microsoft Windows family of operating systems were supported. [2]

Linux drivers

There was discussion of a driver for Linux in 2008. [8] An open source driver for Linux on Google Code used the network block device technology, [9] but because this is a block level device, the OS is responsible for creating a filesystem. Consequently, a filesystem created by Linux will not be compatible with one created by Windows.

However, a 2006 post on kerneltrap.org suggested it may be possible to use NTFS-3g on Linux. [10] If possible, this would allow access from both Windows and Linux machines, at the expense of losing features that the proprietary file system offers, such as sharing the device access across multiple machines, as well as mirroring support.

Internet Small Computer Systems Interface or iSCSI is an Internet Protocol-based storage networking standard for linking data storage facilities. iSCSI provides block-level access to storage devices by carrying SCSI commands over a TCP/IP network. iSCSI facilitates data transfers over intranets and to manage storage over long distances. It can be used to transmit data over local area networks (LANs), wide area networks (WANs), or the Internet and can enable location-independent data storage and retrieval.

Network-attached storage Computer data storage server

Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. The term "NAS" can refer to both the technology and systems involved, or a specialized device built for such functionality.

A disk array controller is a device that manages the physical disk drives and presents them to the computer as logical units. It almost always implements hardware RAID, thus it is sometimes referred to as RAID controller. It also often provides additional disk cache.

QEMU Free virtualization and emulation software

QEMU is a free and open-source emulator. It emulates the machine's processor through dynamic binary translation and provides a set of different hardware and device models for the machine, enabling it to run a variety of guest operating systems. It can interoperate with Kernel-based Virtual Machine (KVM) to run virtual machines at near-native speed. QEMU can also do emulation for user-level processes, allowing applications compiled for one architecture to run on another.

Wireless router Device that functions as a router and wireless access point

A wireless router is a device that performs the functions of a router and also includes the functions of a wireless access point. It is used to provide access to the Internet or a private computer network. Depending on the manufacturer and model, it can function in a wired local area network, in a wireless-only LAN, or in a mixed wired and wireless network.

In Linux systems, initrd is a scheme for loading a temporary root file system into memory, to be used as part of the Linux startup process. initrd and initramfs refer to two different methods of achieving this. Both are commonly used to make preparations before the real root file system can be mounted.

The NSLU2 is a network-attached storage (NAS) device made by Linksys introduced in 2004 and discontinued in 2008. It makes USB flash memory and hard disks accessible over a network using the SMB protocol. It was superseded mainly by the NAS200 and in another sense by the WRT600N and WRT300N/350N which both combine a Wi-Fi router with a storage link.

Das U-Boot

Das U-Boot is an open-source, primary boot loader used in embedded devices to package the instructions to boot the device's operating system kernel. It is available for a number of computer architectures, including 68k, ARM, Blackfin, MicroBlaze, MIPS, Nios, SuperH, PPC, RISC-V and x86.

Ceph is an open-source software-defined storage platform that implements object storage on a single distributed computer cluster and provides 3-in-1 interfaces for object-, block- and file-level storage. Ceph aims primarily for completely distributed operation without a single point of failure, scalability to the exabyte level, and to be freely available. Since version 12, Ceph does not rely on other filesystems and can directly manage HDDs and SSDs with its own storage backend BlueStore and can completely self reliantly expose a POSIX filesystem.

Z-SAN is a proprietary type of storage area network licensed by Zetera corporation. Z-SAN hardware is bundled with a modified version of SAN-FS, which is a shared disk file system driver and management software product SAN File System (SFS) made by DataPlow. The shared disk file system allows multiple computers to access the same volume at block level. Zetera calls their version of the file system Z-SAN.

Network block device

On Linux, network block device (NBD) is a network protocol that can be used to forward a block device from one machine to a second machine. As an example, a local machine can access a hard disk drive that is attached to another computer.

ElephantDrive is a storage virtualization service used primarily as an online backup tool, but also as a remote access service/collaboration tool. The service runs on Windows, Mac, Linux, iOS, and Android platforms, and allows users to create simple automated backups for protecting data by moving it into cloud-based ElephantDrive account.

In Unix-like operating systems, a device file or special file is an interface to a device driver that appears in a file system as if it were an ordinary file. There are also special files in DOS, OS/2, and Windows. These special files allow an application program to interact with a device by using its device driver via standard input/output system calls. Using standard system calls simplifies many programming tasks, and leads to consistent user-space I/O mechanisms regardless of device features and functions.

Storage area network Network which provides access to consolidated, block-level data storage

A storage area network (SAN) or storage network is a computer network which provides access to consolidated, block-level data storage. SANs are primarily used to access data storage devices, such as disk arrays and tape libraries from servers so that the devices appear to the operating system as direct-attached storage. A SAN typically is a dedicated network of storage devices not accessible through the local area network (LAN).
