Two Myths about RAID – Busted

June 29, 2011

As everybody knows that when it comes to RAID, there are certain configuration myths that everybody seems to know:

1. RAID 10 is a requirement for databases. This is no longer the case. Today’s RAID controllers are much more dynamic that it once was as a combination of 400GHz and higher ASICS and IO processors as well as better algorithms have lessened the advantages of RAID 10.

2. RAID 1 configuration is perfect for holding the operating system. Actually this is false – small partition of the OS or applications from a RAID 5/6 is more than adequate. However, with the movement towards centralized storage, shared by high server counts, there is a justification to hold the operating system in the server and protect it with a mirror only because it is not practical to build multi-spindle performance effective RAID5/6 sets in 1U servers or blades.

DNF Security Releases New Products

May 3, 2010

The wait is finally over! We finally unveiled our newest IP surveillance storage products. The Falcon- DL (Diskless Server) and Falcon-BVMS (Bunch of Video Management Software) are the latest additions to our Falcon product family series.

Falcon-DL is a series of diskless IP video recording and management servers. Featuring an energy-saving diskless design, Falcon-DL servers boot directly from DNF Security’s Seahawk line of Internet Protocol (IP) storage area network (SAN) devices to provide superior data protection, optimum mean time to repair (MTTR) and significant cost savings.

The Falcon-BVMS incorporates multiple VMS and integrated RAID protected shared video storage within a single physical hardware. The configuration allows users to have fewer points of management, save on energy expenses, and lower total cost of ownership (TCO).

For information about the Falcon-DL and Falcon-BVMS, please check out our press releases or contact our sales team.

New RAIDML Offers Extreme Protection

November 23, 2009

We just introduced RAIDML™, a new multi-level (ML) approach that provides the highest levels of data protection for mission-critical files and applications.  RAIDML is now an integrated part of StoneFly’s Voyager HA IP SAN, which offers the ability to create No Single Point of Failure (NSPOF) volumes as well as RAID 5 or 6 protected volumes.  Both NSPOF and traditional RAID sets with comprehensive auto fail-over and fail-back capabilities are protected.  The creation of RAIDML saves costs and reduces the need for doubling drives to meet NSPOF requirements.  Use our  RAID calculator to help choose the RAID level that’s right for you. To read more about our new RAIDML features, check out the news release.

RAIDML: Multi-Level Data Protection

October 12, 2009

What does “No Single Point of Failure” (NSPOF) really mean? If you read it at face value, you may conclude that it is the highest level of data protection.  There are several ways to achieve NSPOF on your volumes: mirroring ( RAID 1); mirroring and striping (RAID 10 or 0+1); complete subsystem mirroring (RAID51 or RAID61); or host based applications that manage mirroring. With these conventional NSPOF methods, you are only doubling the disk count, and essentially doubling the entire subsystems cost.

With StoneFly’s new RAIDML configuration, you can create NSPOF volumes and purely RAID5 or 6 protected volumes, and do it in a single storage unit or across multiple storage units.

Here is a highlight of the benefits:

  • Flexible expansion at RAID and iSCSI volume levels
  • Targeted NSPOF iSCSI volume(s) coexist with standard RAID5 and 6 iSCSI volumes
  • Auto fail-over and fall-back protection
  • No 100% drive count penalty
  • Advanced StoneFusion volume management

Do drives come with that RAID?

May 4, 2009

This post is brought to you by the worst pickup line ever.

Prospective customers always ask…

Can I purchase your system without drives? They are available on the open market at a much lower cost.

And I agree.  It is always easy to find a low price on hard drives.  But what’s the cost of your time?  How much time do you spend finding the best deal?  And more importantly, how much time do you spend when you have a drive failure getting the replacement part?

From experience, we found it took far too long. And we have relationships with our drive manufacturers. Sometimes we wait 2 weeks for a replacement! I don’t know if you have two weeks to wait.  To solve the problem, or at least reduce its impact on you, we created our RAID certification process.With RAID Certified drives, DNF customers experience a 50% lower drive failure rate compare to standard and RAID edition drives.

So my short answer to the prospective customers…

We spend 120 hours testing each drive for you, so you won’t have to waste time replacing one.
