The beginning of the end of FCoE

Never bet against Ethernet!

I am sure many IT experts and practitioners would agree. In the past 30 years or so, Ethernet has fought and won against many so-called would be “Ethernet killers”. The one that stood out for me was ATM (Asynchronous Transfer Mode) because in my past job, I implemented NFS over ATM, running in LANE (LAN Emulation) mode in a NetApp filer setup in Sarawak Shell.

That was more than 10 years ago. And 10 years ago, ATM was hot technology. It was touted as the next generation network technology and supposed to unify the voice, data and network together. ATM also had better framing and QOS (Quality-of-Service) control and offers several modes of traffic shaping and policies. And today, ATM is reduced to a niche telecommunication protocol, and do not participate much in the LAN technology space.

That was the networking space. The storage networking space is dominated by Fibre Channel for almost 15 years. Fibre Channel is a serial technology that replaced the channel-based technology of SCSI in the enterprise. And Fibre Channel has also grown leaps and bounds, dominating the SAN (Storage Area Network) landscape with speeds up to 16Gbit/sec today.

When the networking world and storage networking world collided (I mean combined) with Fibre Channel over Ethernet (FCoE) technology some years back, one has got to give some time soon. Yup, FCoE was really hot 2 years ago, but where is it today? Is Cisco still singing about FCoE like it used to? What about the other storage vendors that used to have at least 1 FCoE slide in their product presentation?

Welcome to the world of IT hypes! FCoE benefits? Ability to carry LAN and SAN traffic with one piece of wire. 10 Gigabit-style, baby!


Run free … Symantec FileStore

It has been a rough and tough 3 weeks and I missed writing my blog. Last week, the toughest of the 3, was my CompTIA Storage+ training to Symantec SEs in Malaysia. They were a great crowd, and I loved it but I was really tired after that.

One exciting news during that week was the ouster of long time employee, and CEO of Symantec, Enrique Salem and replacing him with Steve Bennett, their Chairman. The news of that unfortunate event can be read from here and here. And almost hours after that, the calls to break up the Veritas portion of Symantec came up and putting pressure on the board of directors in Symantec to either spin-off the entity or sell it off.

To be fair, many observers, including me, believed that the marriage between Symantec and Veritas in 2005 wasn’t really what you would call a “match made in heaven”. It was more like strange bedfellows to me. And there was an internal joke (one that I could not verify) about the Veritas CEO, Gary Bloom’s promise to the Veritas board when he joined them from Oracle in 2000.

It went like this:

Gary Bloom promised the Veritas board of directors in 2000 that he would be able to bring Veritas to a USD$5 billion dollar company in 5 years time. Nearing the end of the 5 years in 2005, Gary fulfilled his promise by merging with Symantec, instantly making Veritas a USD$5 billion dollar company.”

Note: This is just an inside joke which I heard from a Veritas friend back in 2005, and by no means put Gary Bloom in a bad light. If I did, I apologize.

But back to the present. Our class last week brought up the subject of Symantec FileStore. When it first came out in October 2009, I thought it was an interesting solution. For once, I thought there was something could “out filesystem” NetApp’s ONTAP and WAFL, because Veritas had one of the best scale-out, clustered file systems. They just haven’t figured out the front end protocols yet, where NAS and iSCSI reigned. Veritas File System (VxFS) and Veritas Cluster File System as part of Veritas Cluster Server (VCS) was mature and proven in the enterprise. Along with Veritas Volume Manager (VxVM), this was perhaps THE best file system/volume management suite around. Mind you, ZFS hasn’t reached the level of prominence yet at that time.
