Hardware Used in Storage Backup and Recovery

This article mainly related with storage backup and recovery. It describes what are all the hardware’s used in the storage backup and recovery technologies. So many hardware components used in the Storage Backup areas. It is not the article to bring out the functionalities of that hardware parts. It gives the information and related technical details of that hardware used in the storage backup and recovery technology.

There are three main important hardware’s are used in the storage backup and recovery technology. They are Server, Subsystems and Switches. Each one has its own hardware parts. Let’s see the information and technical details of this hardware parts.

Server Master Server

The Master server performs all Backup administrative functions and controls the backup scheduling for each media server. The requirements needed for Master Server,

· Processors

· Memory

· I/O Connectivity

· Operating System

· Backup Software

Media Server

The media server performs the backup operations under the direction of the master, with all backup data stored locally on the media server and its respective storage devices. The same above Master Server requirements are applicable to Media Server also.

DAS, SAN, NAS Storage Subsystems

Direct attached storage (DAS), storage area network (SAN), and network-attached storage (NAS) are the three basic types of storage subsystems used in Storage backup hardware management. DAS is the basic building block in a storage system, and it can be employed directly or indirectly when used inside SAN and NAS systems. NAS is the highest layer of storage and can be built on top of a SAN or DAS storage system. SAN is somewhere between a DAS and a NAS.

Hardware used in the Storage subsystem

SCSI

It is abbreviated like Small Computer System Interface. It is the famous storage subsystem component used in all medium and small level computer interfaces. A mechanism called ‘Cable Sharing’ used here. It can support the data transfer rate up to 320 MB/s.

PATA

Parallel Advanced technology Attachment is shortly named as PATA. It can support data transfer up to 133 MB/s. Nowadays SATA replaces this PATA in all areas. But the recent version UDMA133 is used in some subsystems depends upon the customer requirement.

SATA

Serial Advanced Technology Attachment is commonly known as SATA. It is the very common hard disk interface used in all personal systems. One SATA port permits one device to connect to it.

SAS

It means Serial Attached SCSI. The name itself tells, it can be seen as a merged SCSI and SATA interface. It has various data transfer rates like 185, 374, 750, and 1,500 MB/s. SATA devices can connect to SAS but SAS devices can’t connect with SATA ports. It is specifically designed for the high-end servers. SAS offers the best of SCSI and SATA.

Fibre Channel has a main advantage of its length. It works the same like SATA, but it can covers the distance up to 2kms (Example: Single Mode Fibre). FC offers speeds of 100, 200, and 400 MB/s.

iSCSI

Internet SCSI is shortly known as iSCSI. It is normally used in all LANs. It is Low-cost alternative to FC. Easier to manage because it uses the common TCP/IP protocol and common Ethernet switches.

AoE

ATA over Ethernet. It is a very low cost alternative to iSCSI. It encapsulates ATA commands into low-level Ethernet frames and avoids using TCP/IP. A lot of add-on initiator/target software will support both iSCSI and AoE.

Ethernet Switches

A switch is something that is used to turn on or off various electronic devices. However, in computer networking, a switch is used to connect multiple computers with each other. Since it is an external device it becomes part of the hardware peripherals used in the operation of storage backup and recovery. This connection has done within an existing Local Area network (LAN) only and is identical to an Ethernet hub in terms of appearance except with more intelligence. These switches not only receive data packets, but also have the ability to inspect them before passing them on to the next computer. That is, they can figure out the source, the contents of the data, and identify the destination as well. Because of this uniqueness; it sends the data to the relevant connected system only, thereby using less bandwidth at high performance rates. Ethernet switches were used to provide connections and link aggregation between the backup clients, media servers, and master server using network speeds of 100 Mb/sec, 1 Gb/sec, and 10 Gb/sec.

SAN Switches

SAN switches were used to provide Fibre Channel connections between the Backup media servers and the tape libraries. The below listed companies are working with SAN switches worldwide.

Used Cisco

It is not true that quality can only be experienced from products that are brand new. Take a used Cisco for example. A used Cisco switch works in the same way as that or a brand new one. Aside from that, a used Cisco costs cheaper, thus, making it a wiser option. The important thing when buying a used Cisco is to find the right market and seller.

Typically, buying a used Cisco hardware is very challenging thing to do. Although the secondary market is always a good place to find used IT equipment and components like a used Cisco, it is still not wise to just blindly trust a reseller out of the blue. You can’t just pick a used Cisco reseller and decide to buy at once.

You should remember that a used Cisco is considered an investment on your part thus you should be extra careful. The main idea in buying a used Cisco is that it should be able to provide benefits to the company in the long run.

You should do thorough research when looking for a good used Cisco. Ideally, you should be able to ask several questions to the reseller to make sure that you are indeed buying a quality used Cisco. A good used Cisco reseller should have a good track record. You should be able to find out where the reseller’s supply comes from and does he or she follow standard measures when selling used products.

A good reseller also provides a good customer service and even offers product warranties. A product warranty is very important. It can guarantee your money back given that the product is not functioning well. Make sure to ask around and do a thorough research before purchasing the item. This can help avoid future troubles.

Juniper’s relationship with Packet Design

In Newsletter 26 October, we noted that the most common rumor we heard was, was acquired by Juniper Riverbed would. In this issue, we find that for a number of reasons, we do not assume that Juniper would Riverbed. We explained, for example, to sell in the service, but certainly not Riverbed is first a rapid business-focused companies. In contrast, DNA Juniper clearly in the market for service providers.

Part of the agreement, Juniper announced that with Packet Design is the kind of partnership with OEM direct sales Juniper Packet Design Route Analytics does not sell products. announced as part of its announcement, as well as Juniper, they offer a platform for spatial development called Juno. Packet Design Route Analyzer product is one of the first solutions, which lives in the space of Juno.

Contrary to rumors of the acquisition of Riverbed, Juniper recently announced relationship with Packet Design is very much sense. This follows because Packet Design Route Analytics produces some of the challenges that occur in very large networks, targeted – both corporate and service provider.

Juniper’s relationship with Packet Design

For example, any of the products Packet Design Route Analytics for professionals is precisely to model the evolution of the network before their implementation, to allow. Another function of these products is to provide visibility, analysis and diagnosis of problems that arise in the position of the signal. To do this, have an analytical solution route has an understanding of how IP networks deliver exactly the application traffic. This requires continuous monitoring in real time, creating and maintaining a map of all roads and network-wide IP traffic flows passing through these roads. This implies that the solution analysis route must be notified in a position, any change in the lanes is controlled by the host and IP routing protocols.

We said that this relationship makes sense in part because networks are increasingly complex to administer Packet Design Route Analytics Products, Juniper understands the complexity and definitely large and complex networks.

The ads are part of Juniper interesting because they show that, despite the impression that it takes a lot of innovation in network. To reinforce this concept is a package design Be one of the panels at the next Jim Interop Conference in New York. The panel is titled “Break Through networking technologies. If you are to be at the conference, try to attend the panel, as it should be very revealing.
