If you work with EMC Symmetrix systems, you know the importance of VCMDB. Introduced with Symmetrix 4.0 and used in every generation after that, VCMDB stands for Volume Control Manager Database). Also in the latest generation of systems the VCM device is at times also referenced as VCM Gatekeeper.
EMC Symmetrix BIN file, largely an unknown topic in the storage industry and practically there is no available information related to it. This post is just an attempt to shed some light as to what a BIN file is, how it works, what’s in it and why is it essential with the Enginuity code.
Very little is known about the Symmetrix File System largely known as SFS. Symmetrix File System is an EMC IP and practically only used within the Symmetrix environment for housekeeping, security, access control, stats collection, performance data, algorithm selection, etc.
So this year will mark the history of the Symmetrix products, 20 years since its inception and the Symmetrix has come long ways. Initially released in 1990, today’s Symmetrix does not come any close to what the product was 20 years ago. The underlying code (Enginuity) is what drives and gives the Symmetrix its personality. Symmetrix was a compute / storage beast 20 years ago and so it is today.
FAST (FULLY AUTOMATED STORAGE TIERING). FAST made a debut in the storage market yesterday (12/08/09). Finally after the market buzz we got a preview of the product in terms of its features, functionality, characteristics, possible shortcomings and use cases. This blog post focuses on the features, the drawbacks and some applications around FAST. By no means is this a comprehensive or an exhaustive list of the above.
Truly this was one of the most awaited products of 2009 from EMC after the initial announcement by EMC back in April 2009 along with the release of Symmetrix V-Max. Along with FAST, EMC has also introduced some new enhancements to the EMC Symmetrix V-Max, Clariion CX4 and Celerra NS platforms. Currently FAST will be available on the above 3 platforms at debut and will provide automated storage tiering “in-the-box†for Symmetrix V-Max, “in-the-box†for Clariion CX4 and “out-of-box†for Celerra NS platforms.
See the Drobo in Action, a wide coverage of various Drobo Performance Stats. Here are some stats collected with running Drobo as a direct attached storage and using some benchmarking tools to compile these results. All the performance stats are collected using different criteria’s that can affect the performance of the Drobo. Also used various connection methods including USB and Firewire to obtain these stats.
It has been an exciting month, some new details are emerging related to automated storage tiering, workload distributions, workflow automation, SLA’s, QoS and how Policy based storage management can help solve these challenges.
Enhancements to EMC Symmetrix V-Max systems is possibly around the corner (FY09 Q4). FAST (Fully Automated Storage Tiering) is due this quarter and will be one of the most awaited software release in the enterprise storage space by EMC. Bundled together with FAST, possibly a new microcode version the enables FAST (its associated features) and other expected enhancements.
Clearly ORACLE is targeting IBM and NCR – Teradata products with the release of the SUN ORACLE EXADATA Version 2 platform. It was obvious listening to Mr. Larry Ellison, where he used the word “THEY” numerous times signaling towards IBM and NCR. Though it was not said during the presentation, “THEY” could include HP as well. At this point without the final approval of the SUN purchase, it wouldn’t make a lot of sense for ORACLE to make another enemy, HP.
