iSCSI Vs Fibre Channel - Battle Continues

February 15, 2012 | Comments: 0 | Views: 157

There was a time that some claimed that iSCSI is not mature and is not suitable to serve the storage needs of high demanding data centers.

Those days have passed, and even those companies who promoted Fibre Channel, are starting to offer iSCSI products. There is no argument anymore that iSCSI has taken hold as the interface of the choice for new storage installations. All recent market studies have shown that FC storage market has been either steady or has had a slight year to year improvement, while iSCSI storage market has been on the double digit rise year after year.

All features that have been once only available on high end FC SANs are now available in iSCSI storage products. All the arguments about performance advantages of Fibre Channel are disappearing since 10G iSCSI has started shipping in numbers. And most important of all, there is no argument anymore that iSCSI storage costs are a lot less than a FC SAN with equivalent performance and features.Only those companies who do not have iSCSI storage are still trying to promote FC. But users are smart and do not see any compelling argument anymore to buy FC SAN.

Having said all that, we do not think Fibre Channel is going to die anytime soon. As like any other technology, it takes a long time for an established technology to wind down and get replaced by another one. SCSI storage is still available when some predicted it will die 10 years ago. But from all market indications it is obvious that storage trends are moving toward IP Storage rather than Fibre Channel.

In summary, iSCSI, when properly implemented, provides high performance, hence making it a suitable to deploy in core applications. iSCSI is easy to understand and lower cost makes it a strong choice for medium to large enterprises. Having an end-to-end Ethernet IP environment is an added benefit to iSCSI. A properly designed iSCSI infrastructure and storage platform is good enough to handle any storage application currently handled by a Fibre Channel SAN.

With Cloud Storage gaining hype in providing data solutions and recent developments in its technology, there is a mis-conception that local storage will soon become outdated.

As much as Cloud storage is useful for some applications, local storage is preferred for applications that demand better storage options. This is so because large enterprise applications need high speed access to their storage, which is not practically possible by cloud storage due to the low WAN access speed to the cloud.

Also, in Local storage, you are in control of your data, it is accessible without an internet connection and more secure when compared to the data stored on a cloud.

Although cloud storage is perfect for enterprise computing, local storage benefits outweigh cloud storage.
