SAN Design & Deployment Engr : If you aspire to be a software architect & if you have the right skill for the same - this is a role you can fit into. Well this is something which needs atleast 1-2 years of SAN experience interms of actual hands on exposure in deployment of SAN infrastructure. ( We will include some Real Life implementation details & lots of graphics to help you understand this better )

SAN Administrator : Are you good in networking and system administration then there are loads of SAN administrator openings ( We will post the job requirements for each of these requirements in our future postings)

SAN Applications developer : If u r good in development of C/Unix or say any programming then you can very well fit into this role - U just need to have a good understanding of SAN fundamentals & very good programming skillset.

SAN device driver and Firmware development engineer for different components such host controllers,Arrays,Switches : All those embedded systems experts here is a golden opportunity for you - If you have good experience in device driver and Firmware development and though you are new to SAN you still are very much in demand . Yes you can get very good salary for your high skills.

SAN Support Engineer : Freshers here is a silver line for you - This is the most easiest way for a job hunter to get into SAN jobs. Yes it is not a high demanding job initially and it is not too tough and it is actually going to help you build your career. A support engineer in SAN is expected to have a fair SAN exposure ( YOu will get training once you join so dont worry :) . He is responsible to handle customer service requests & will be on call to resolve those technical issues and will build his expertise along the way - You get promotions and big pay as well .
No - This is not a call center kind of job. But this is far better interms of helping you learn as well as Earn in a technical environment.

Backup and Recovery Administrators : take any software industry they need a "Backup and Recovery Administrator" actually they need many. So this is also very much suited for freshers & new comers. We will go into details about this job requirement & how can a newcomer start his preparation to get a job in some similar roles. SAN Jobs are great for anyone to build their tech as well as domain knowledge.

SAN testing engineers: Testing Engineers in SAN this job is sooo much in demand that We are planning to have a detailed blogpost entirely on this subject. For time being - yes this is also very much suited for freshers/newcomers and compared to all other jobs this is an easy to get , easy to win the interviews kind of jobs.

We will have more postings coming twice daily so keep reading & refer more people to read this blog.

SAN Hardware building blogs- HUBs

Hubs only understand the arbitrated loop topology. When you connect a device to a hub, it will cause the arbitrated loop that the hub is managing to re-initialize. The device will be assigned an AL_PA (arbitrated loop physical address), and it will begin arbitration when it needs to communicate with another device on the loop.

Types of Hubs:-

There are managed (i.e., "smart") hubs and unmanaged (i.e., "dumb") hubs. An unmanaged hub is unable to close the loop when a device on the loop is malfunctioning; therefore, a single bad device can disable the entire loop. A managed hub could detect the bad device and remove it from the loop, allowing the rest of the loop to function normally.

Although there are plenty of unmanaged hubs available, the cost difference between managed and unmanaged hubs is minimal, and the functionality difference between them is quite great. When considering a new SAN, one should also consider whether a hub is even appropriate. The cost difference between hubs and switches gets smaller and smaller every day, and the functionality difference is even greater than the difference between managed and unmanaged hubs. Since arbitrated loop is cheaper than fabric, I have seen a number of sites build SANs based on hubs and arbitrated loop -- only to rip out the hubs and replace them with switches a year or two later.

SAN Hardware Building Blocks- HBA

HBA-> Host Bus Adapter

 

› Servers connect to the SAN via their Host Bus Adapter, or HBA. This is often referred to as a "Fibre Channel card," or "Fibre Channel NIC." It is simply the SAN equivalent of a SCSI card (i.e., a SCSI HBA). Some HBAs may use fiber, and some HBAs may use copper. Regardless of the physical layer, the HBA is what is used to connect the servers to the SAN.

› Note that there are two main types of lasers in today's HBAs: OFC and Non-OFC. OFC (optical fiber control) devices use a hand-shaking method to ensure that they do not transmit a laser pulse if there is nothing connecting to the HBA. (This is for safety reasons, since a high-powered laser can cause permanent damage to your eyesight.) Non-OFC devices employ no such handshaking, and will transmit even if a device is not connected. Believe it or not, Non-O Although there are some fiber-optic-ready host adapters, most HBAs come with an electrical DB-9 or HSSD serial connector, so using them with fibe optic cables requires a Media Interface Adapter (MIA) to convert between electrical and optical signals. MIAs can also be used to convert electrical Fibre Channel devices for use with fiber optics.

› FC devices are actually quite common, due to the cost associated in making an OFC device. Therefore, please do not look directly into an HBA. You may regret it!
