Fibre Channel Network Architecture brief introduction

FC Network protocol & architecture are other important topics any storage professional should be aware of.
Fibre Channel Protocol


Fibre Channel Overview
Fibre Channel is a networking standard that is designed to move data through specific devices at specific speeds. Initially, Fibre Channel was used primarily to attach servers to a storage device, such as a RAID array or a tape backup device. More recently, Fibre Channel has evolved as the architecture of choice for many storage area networks. Fibre Channel is ideally suited to this role because it is very reliable, very scalable, and very flexible. It's possible to add more storage without disrupting operations, use a number of backup schemes that don't load the main network, and manage very large data collections that span multiple disks.

Fibre Channel is a high speed (100 to 800 Mbps) medium used for data transfer and storage. Fibre Channel provides a logical bi-directional, point-to-point connection between a host and a device. It is essentially a serial data channel created over fiber optic cabling which makes it possible to transfer data at much greater distances than SCSI and ATA interfaces.

Fibre Channel is designed to work with either copper wires or with fiber. Although copper is used only for shorter distances, a variety of copper mediums can be used, including telephone wire or coaxial cable. If fiber optic cable is used, distances of about six miles can be achieved with minimal loss of speed. Another advantage of dedicated channel based communication is its ability to provide increased bandwidth than network based links.

Features and Benefits

Storage Area Networks are not new ideas in data storage, however they are increasing in popularity due to high demand by users who need to store large volumes of data. A SAN is a group of storage devices connected via a network of connections to host computer or server. The primary advantages of SANs are:
* Storage resource pooling/sharing
* LAN and server-free backup
* Centralized storage resource management
* Data sharing - Large number of users
* Performance - High Speed, Low Latency
* Distance (>10KM)

Architecture
Channels and networks are the two primary ways that data is transferred between devices. Fibre Channel uses channels and frames instead of packets to move data. Each frame is approximately 2KB in size. Of this amount, 1.5 percent is header information. Channels transfer data through switched or direct point-to-point connections and they work by creating a fixed connection between the source and destination devices until the transfer is complete.

Connections are made on Fibre Channel systems through "interconnection components" including switches, hubs, and bridges. The ability of Fibre Channel to use different interconnect devices makes it scalable depending on user needs. For small Fibre Channel networks, hubs and bridges may be used for connecting devices in a topology called Fiber Channel arbitrated Loop (FC- AL). As Fibre Channel networks get larger and network demands increase, switching may be implemented. A switched Fibre Channel network is called a fabric.

Fabric topology permits multiple paths between two ports on the Fabric. Loop topology, on the other hand, there can only be one active circuit at a time. Loop and Fabric topologies can be combined to provide both connectivity and performance. If a link in a point-to-point topology fails, communication between that pair of ports stops. Communication between other point-to-point connected Ports continues.

Fiber optics are excellent for transmitting data across a network because they are reliable. They do not have the same problems that are associated with copper cabling such as attenuation (loss of signal strength) and noise. It is also more secure than copper because crosstalk does not occur with Fiber Optic cables. Fibre Channel traffic can also be transmitted over other cable types such as copper, coaxial cables or Unshielded twisted pair (UTP) wires.

Class of Service - Fibre Channel technology makes use of classes of service to define communication between devices.

* Class 1 a dedicated channel between two connection devices. In this configuration, if a host and a device are connected, no other host can use that connection. The advantage of using service class 1 is speed and reliability.
* Class 2 is known as a "connectionless" service. It a frame-switched link that guarantees delivery of packets from device to device and packet receipt acknowledgments.
* Class 3 is called unacknowledged connectionless service and is good for broadcasts. This configuration allows multiple transmissions to be sent across the Fibre Channel fabric to multiple devices.
* Class 4 is called "intermix", which creates a dedicated connection but it also allows class 2 traffic to access the link. This method is very efficient and it allows for greater bandwidth because more than one connection can access the system at any time.

Storage architecture SAN architecture FC Network architecture

One of the Top question asked either in a Storage job profile interview or while attending a Client meeting is "Explain your system architecture". Based on whats their interest they may be interested to know about your
- Storage architecture
- SAN architecture
- FC Network architectiure

So this post has few images & some good links to help you learn more on these Very important topics

Storage architecture: Storage architecture design should follow a structured approach to ensure that the correct solution is adopted by the organization. The three basic types of storage architectures that are discussed in this blueprint(microsoft.com/technet/solutionaccelerators/wssra/raguide/ArchitectureBlueprints/rbabst_2.mspx) are:
- Distributed Storage
- Hybrid Storage
- Centralized Storage
Each of these storage architecture types defines a storage pattern that can be used as a starting point for providing guidance on how the storage should integrate with the business needs of an organization. If business needs are not communicated when enterprise architecture issues are being considered, it is easy for new projects to focus only on their own requirements and miss the wider picture that an architecture encompasses.

A structured design process for a complete enterprise storage solution consists of:
•Determining the storage requirements.
•Choosing the storage technologies.
•Defining fault tolerance technologies.
•Defining backup and recovery technologies.

iSCSI Storage Solutions to solve Business Requirements

Continuing the previous post on iSCSI . This is an important topic for Storage professionals as its going to be the next major trend.

Adaptec iSCSI initiator


iSCSI host bus adapters (HBAs) are network interface controllers that incorporate a TCP Offload Engine with onboard iSCSI processing. iSCSI HBAs are usually abstracted purely as SCSI controllers by the operating system driver system. In this case, the HBA is not a part of the system network stack. Recently there has been considerable effort in providing standard vendor-independent iSCSI management facilities via operating system driver interfaces. These standard interfaces also work with software initiators.

Qlogic iSCSI HBA

Since iSCSI HBAs offload considerable processing in the iSCSI stack, interrupt generation is less than comparable software initiator setups. Applications leaving few spare CPU cycles should benefit from the use of a dedicated HBA.

HP Fires a Bullet through its Storage array for a Stress Test


iSCSI HBAs have the advantage of including PCI option ROMS to allow booting from iSCSI targets. Alternative iSCSI boot methods with software initiators would require substantial work.

The following vendors have developed iSCSI HBAs:

* Adaptec (Product is discontinued.)
* Alacritech
* Intel (Product is discontinued.)
* Qlogic
* Silverback Systems External Link

Targets
Most industry focus has been placed on creating iSCSI disk targets though iSCSI tape and medium changer targets are popular as well. So far, physical devices have not featured native iSCSI interfaces on a component level. Instead, devices with SCSI Parallel Interface or Fibre Channel interfaces are bridged by using iSCSI target software, external bridges, or controllers internal to the device enclosure.

Alternatively, disk and tape targets can be virtualizations. Rather than representing an actual physical device, an emulated virtual device is presented. The underlying implementation can deviate drastically from the presented target as is done with Virtual Tape Library (VTL) solutions. VTLs use disk storage for storing data written to virtual tapes. As with actual physical devices, virtual targets are presented by using iSCSI target software, external bridges, or controllers internal to the device enclosure.

Addressing and Name formats
iSCSI provides two name formats for different types of naming authorities:

* iSCSI Qualified Name (IQN), Format: iqn.yyyy-mm.{reversed domain name} (e.g. iqn.2001-04.com.acme:storage.tape.sys1.xyz)
* Extended Unique Identifier (EUI), Format: eui.{EUI-64 bit address} (e.g. eui.02004567A425678D)

In the case of IQN the address is qualified by a date (yyyy-mm) since a domain name can expire or be acquired by another entity. EUI is provided by the IEEE Registration authority in accordance with EUI-64 standard.

Each target is defined by three or four fields:
HostNameOrAddress PortNumber iSCSIName CHAPSecret (optional)

Example:
iscsi.fake.com 3260 iqn.2003-01.com.ibm:00.fcd0ab21.shark128 "123ismysecretpassword"

What is iSCSI Storage Solution Is it one of the Top Storage Technologies

Email roger.smithson@gmail.com for a FREE SAN STUDENT GUIDE pdf file


If you aspire to be a professional in Storage IT company its a MUST to know FC & iSCSI. There was a previous post about FC & below is a brief on iSCSI .
As per Wikipedia's definition Internet SCSI (iSCSI) is a network protocol standard, officially ratified on 2003-02-11 by the Internet Engineering Task Force, that allows the use of the SCSI protocol over TCP/IP networks. iSCSI is a transport layer protocol in the SCSI-3 specifications framework. Other protocols in the transport layer include SCSI Parallel Interface and Fibre Channel.
The iSCSI (pronounced eye-skuzzy) protocol uses TCP/IP for its data transfer. Unlike other network storage protocols, such as Fibre Channel (which is the foundation of most SANs), it requires only the simple and ubiquitous Ethernet interface (or any other TCP/IP-capable network) to operate. This enables low-cost centralization of storage without all of the usual expense and incompatibility normally associated with Fibre Channel storage area networks.

Acceptance of iSCSI in corporate production environments has accelerated now that Gigabit Ethernet is common. Building iSCSI-based Storage Area Networks (SAN) has become a less costly but worthy alternative to creating Fibre Channel-based SANs.

iSCSI terminology and how iSCSI can be used by an OS

An iSCSI initiator, in client/server terminology, is akin to a client device that connects to some service offered by the server (in this case an iSCSI target). An iSCSI target is akin to a server, in that it provides block level access to its storage media (usually a hard drive, but can be other types of SCSI devices if the iSCSI target software supports them.) The primary difference between a regular client/server system and an iSCSI initiator/target system is that while many clients can be simultaneously served by a single server (many-to-one), only one iSCSI initiator can talk to a given iSCSI target at a time (one-to-one).

iSCSI can be used to give an OS block-level access to a remote device (one attached to another computer likely on the same LAN). Depending on the types of devices supported by the iSCSI target, this block-level access can be used to build RAID volumes using remote disks, or to connect and use remote DVD/CD-writers and scanners, or to simply access additional storage space. iSCSI devices are not shared by iSCSI amongst multiple computers at the same time; instead the OS in control of the iSCSI device is responsible for controlling remote access to the device. The initiator and the OS that it is running on will determine how the iSCSI device appears, and whether it is a /dev entry or gets a drive letter or something else.
Source : Weblinkhttp://en.wikipedia.org/wiki/Iscsi


ESG reports that it has identified 2500 iSCSI SAN deployments, and expects deployments to increase substantially in 2005. According to another ESG study of 130 SMB end users, 17% have already deployed an iSCSI SAN, and another 42% are planning to deploy iSCSI SANs by mid 2006. Spectra Logic’s interactions with customers support ESG’s expectations, given the increasing rate of Spectra Logic’s iSCSI products sales, the increasing support of iSCSI drivers/initiators by major operating systems, and the major vendor commitments to the technology.

Microsoft continues to be a major force behind iSCSI, pushing to make iSCSI SAN deployment even easier and even more “risk-free” to the masses. Considering that most of the growth within the storage market will come from small to medium businesses–environments heavily dominated by Windows and Linux–other major storage vendors are certainly enticed to work with MS to make “iSCSI SANs for the masses” a reality. Economics of scale make their decision and direction an easy one, further eased in that iSCSI is already supported in most operating systems.

Salary in Software Companies in India,delhi,noida,bangalore,chennai,mumbai

Salary Package in Software Companies in India

After receiving lots emails about salaries in India, I thought of gathering some more facts from aquintances in indian companies, recruiters and others who have been involved in IT placement sector. This is a very ROUGH estimate & not to be taken as serious data.Indian Salary are based on the concept of CTC ( Cost to Company ) and that makes it very hard to compare offers of any two IT companies. There are companies that include every detail including their contribution to PF(Provident Fund), and other companies that try to be fair by including only the real components that are being given to you.

There seems to be offers which include performance bonus in the overall offer with a clause that it is based on overall performance of the company. MNC's and some companies do not play these games, so you are better off taking their offers as the baseline. I tried to eliminate the performance components in the calculations below. Be wary of some companies that include variable components into CTC.

General Salary Ranges in some software companies are listed below.. [ Most companies fall into this range including Big companies like satyam, infosys, wipro ... ]. Numbers below are estimated CTC in terms of Salary Per Annum in INR(indian rupees) where 1 Lakh is 100,000INR.

Entry Level / Fresh Graduates [ 0 to 2 years ] : 2.5 to 4.8 Lakhs. I have seen this being as high as 6 Lakhs in Bangalore.
Junior Positions [ 1 to 4 years ] : 3.5 to 7 Lakhs
Mid level [ 3 to 6 years ] : 5 to 11 Lakhs
Sr Level [ 6 and Above, Project Manager, Lead etc ] : 9 to 17 Lakhs [ Too much competition for these jobs ]
Leadership [ Delivery, Operations, HR etc. 12+ Years ] : 15 to 25 Lakhs [ Internal candidates get the first preference here. ]
Sr. Leadership [ Operations Head, VP etc ]: 18 to 45 Lakhs
Executive Leadership [ SVP, COO of Biz Unit etc.] : 35 to 70 Lakhs
C Suite of Company [ Country Head, CEO, CFO, CTO ] : Heard of offers ranging from 2 to 7 Crores. This cannot be confirmed, but most recruiters seem to agree with this range.

Now to some spicy cases :

* Entry level offers in 2006 by Microsoft are around 9.5 Lakhs, Google at 12.5 Lakhs, Amazon at 7.5 Lakhs. They are only focusing on top grade schools including the IIT's. Interviews are hard to get through.
* Google, Microsoft, Amazon, Yahoo etc., dont seem to care about the money as long as the candidate is the right fit for their Organization.Some examples I heard of include 25+ Lakhs for testing lead, and around 35+ Lakhs for a Sr. Developer, 78+ Lakhs for a Director.
* MBA's of indian schools like IIM , ISB etc., are starting around 20 Lakhs and going all the way to 1.5 Crores. There were recent examples of 2 MBA grads rejecting a 1 Crore offer to pursue their own enterprise.
* Also companies like Oracle, CSC etc., offering beyond the above grid to attract mid and senior level talent. They have large plans for India and are unable to meet the internal demand.

Is Storage one among the Highly Paid Jobs technology sector

Many blogreaders emailed asking is this one among highly paid jobs segment.
Answer is Yes - this is ONE among a few of IT segments where the salary is really good. Read below that its not just me who is saying that Pay packages in storage are really good but there are lots of online resources which reassure this statement.

I read this on one of the forums dslreports.com, shared by another SAN pro:
"Deep expertise in EMC, Veritas, HDS, McData, Brocade, etc. is certainly hard to find and well-compensated when it is found. I expect a lot of companies looking for SAN experts are dealing with staff that's been lured away by more money.

I just did my first EMC SAN install about 6 months ago and it's a daunting knowledge base to get into. Since a Dell SAN tech. actually handled the real install and configuration and hand-held me through some of the configuration I really only scratched the surface. He zipped through it like it was completely second nature to him, but he's done hundreds of installs of course.

If you have the opportunity to learn SAN I would absolutely take advantage of it. It appears to me that the demand for storage is insatiable and the more skill one has in managing storage networks the better your future will look. If you don't have the opportunity to learn SAN where you are now you may look at signing up for SAN training courses which, while they will not be cheap, will give a foundation to potentially get a foothold in an environment that needs SAN expertise.-boethius"

Another forum writer with nick cdru said :
"I would encourage you to find a job where you do what you love to do, not necessarily the one where you get paid the highest amount. Remember that jobs like this where people get paid alot, there is usually a reason. Either they are highly skilled at what they do or there is no one that knows what they know. Either way it's not something that you can quickly sit down and read a "Dummies Guide to SANs" and pick up in a afternoon. If it was, there would be a whole lot more people doing it and the salary price would be driven down."

According to another Storage related webportal TechTarget's annual Salary Survey, two new entrants into the top 10 list of titles are storage-related. Storage architect which has leapt from nowhere to score the number three spot, behind only CIOs and Internet architects, reports an average salary of $83,368, and average total compensation of $88,763. The position of storage manager has also appeared on the list for the first time. Coming in at number 8, the job has an average salary of $74,400, with average total compensation coming in at $76,300.

The rising importance of storage-related jobs makes sense, as companies continue to realize the importance of maintaining a solid and reliable infrastructure, and are investing accordingly.

So readers you can realise the importance of a Career in Storage & get going.
