Let’s be real for a minute. Dell recognizes the fact that the storage market has become increasing competitive…particularly when it comes to flash-based solutions. Have you noticed that companies out there tend to offer either a hybrid-flash solution or an all-flash solution, but not both…? It’s because they can’t…but Dell Compellent can.

The Dell Compellent SC220 all-flash enclosure has:

  • Twenty-four (24) 2.5” drive bays or slots
  • Twelve (12) of these drive bays are populated with SSD drives (all flash drives)
  • Six (6) 400GB write-intensive SLC SSDs
  • Six (6) 1.6TB read-intensive MLC SSDs
  • Twelve remaining slots can be filled with six-packs of SLC and MLC SSDs

The Dell Compellent SC220 hybrid-flash enclosure has:

  • Twenty-four (24) 2.5” drive bays or slots
  • Twelve (12) of these drive bays are populated with SSD drives
  • Six (6) 400GB write-intensive SLC SSDs
  • Six (6) 1.6TB read-intensive MLC SSDs
  • Remaining twelve (12) drives can be a combination of SSDs and 1TB 7.2K RPM HDDs (rotating disks)

No doubt the SC220 hybrid-flash solution provides some great flexibility and scalability as it provides three (3) tiers of storage while:

  • Being configured to use one or more SC220 flash enclosures with both write- and read-intensive SSDs and HDDs
  • It can also expand capacity with SC220 enclosures
  • Add SC220 enclosures which can use 7.2K, 10K or 15K RPM drives
  • Add SC200 enclosures with large capacity drives
  • Add SC280 enclosures with 4TB 7.2K RPM drives

Talk about flexibility here, particularly with the Dell Compellent hybrid-flash solution(s). Finding Compellent pricing can reveal some good budgetary numbers, but it is recommended you go through a trusted Dell Compellent reseller to create a customized presentation based on your requirements.

Yup, Dell is back in the storage game with some powerful SSD / flash-based solutions…oh, yeah…

The following article-blog (written by Alan Atkinson, GM—Dell | Compellent 6 Aug 2013 12:00 PM ) was given permission to us to share, citations are given at the end of this article:

“Storage Center 6.4 will allow us to fully leverage SSD technology and offer the best performing hosted Exchange service and cloud servers on the market, with the lowest possible latency.” (Jean Caron, Vice-President, Operations, at Sherweb)

The Dell storage portfolio takes a major step forward with the introduction of Storage Center 6.4. This release introduces record Dell Compellent performance and density, at a price point that can change the economics of your data center. These new capabilities have received incredibly positive responses from both our customers and the marketplace as a whole as seen when announced at the Dell Enterprise Forum back in June.

As I talk to customers, they’ve told me that they want greater performance and higher density – all at a lower price point. We listened and now have rolled out….

Flash-optimized solutions designed to improve performance for data-intensive applications and OLTP workloads, optimized with intelligent tiering to cost less than comparable 15K disk drive solutions! [1]

New SC280 dense enclosure, the densest solution of any major vendor in its class with 336TB in 5U. [2]

Storage Center 6.4, which optimizes performance for database & OLTP workloads, amplifies the power of Compellent tiering, and integrates management of block and file.  We’ve reworked our tiering logic to specifically address flash technology.

Today, we’re releasing our Flash-optimized solutions and our SC280 dense enclosure powered by Storage Center 6.4, which helps you manage your expanding storage needs while preserving your capital for sales, marketing and R&D. Storage Center 6.4 is the first storage solution in its class to tier sub-LUN data across traditional rotating drives, write-optimized SSDs and read-optimized SSDs. [3]

Compellent’s leading automated tiering with Data Progression has been enhanced and optimized for flash to provide built-in, extremely granular intelligence that automatically tiers data across multiple SSD types and optimizes performance all while protecting your data. This allows you to experience cost savings by migrating older files automatically down to lower-tier, less-expensive drives while writing and leaving frequently accessed data on faster, Tier 1 drives.

There is this perception that flash-optimized storage is more expensive than spinning disks. This is not the case anymore with the Dell Compellent Flash-optimized solutions that offer flash performance with up to 84% space reduction, up to 90% latency reduction and an approximate 56% pricing reduction compared to traditional spinning arrays. [4]

Flash-optimized solutions can be configured with all SSDs for an all-flash solution, or a combination of SSDs and spinning disk drives for a hybrid-flash solution depending on your data center requirements. Compellent’s Flash-optimized solutions and data progression increase system performance by 75% and can increase storage capacity while reducing solution costs compared to arrays with spinning media. [5]

Complementary to the Flash-optimized solution we are introducing the Compellent SC280 dense enclosure which offers the best rack unit density of any major storage solution. 84 4TB hard drives in a 5 rack unit (RU) space  allows for 67.2TB usable per rack unit, clearly maximizing floor space and creating an all-in-one fast write, bulk storage solution.  You can now have 2PB of storage along with 2 Compellent Storage Center systems in a 48U rack. The SC280 can be used in a solution that tiers data from high-performance, Flash-optimized solutions with SLC and MLC SSD all the way down to high-capacity, cost-optimized storage—all within a single Compellent array.

[1] June 2013 Dell internal list pricing analysis indicates that the Dell Compellent disk drive solution for 37.6 TBs of 15K drives is $440,600 and 42.4 TB of SSD using the Dell Compellent all-flash solution has a list price of $426,741.

You already have a powerful Dell Compellent SAN in place…and perhaps you even have the FluidFS solution of a Compellent FS8600 in place as well. So if you do, you’re going to be excited about what’s coming out later this month: FluidFS v3.

What does this mean…? Everything!

For one, get used to the following term: Fluid Data Reduction. What this will allow you to do is build policy-driven variable-block dedupe and LZPS compression. That’s right, dedupe and compression! Dell’s finally answered the call to its clients’ demands…and it gets better. Here’s a quick breakdown of some of the more common updates and features with FluidFS v3:

  • Support for SMB 2.0, 2.1, and NFSv4
  • Improved Scalability with 10,000 active SMB sessions per appliance
  • Up to 2PB in a single namespace on the FS8600 (with two SC8000s)
  • Access-Based Enumeration to allow you to hide files and directors for which a user does not have access (pretty slick, eh…?)
  • 1GbE to 10GbE Upgrade Path for current 1GbE FluidFS customers
  • Thin Provisioning and Clones – thinly provisioned NAS volumes and RW thin clones of NAS volumes

Some other features include AD as LDAP, Secure LDAP, Full EM integration for FS8600, improved installation experience, and dedicated management port (LOM) for the FS8600.

Be sure to verify these features with any new Compellent pricing you get as some (very few, really) of these features might not be available for iSCSI.

…The new tiered flash technology, first unveiled in June at the Dell Enterprise Forum, combines high-speed SLC flash memory with slower but cheaper MLC flash memory, said Bob Fine, director of product marketing for Dell storage.

Dell then applies its Data Progression auto-tiering software to automatically tier data between the SLC and MLC flash memory and to hard drives, Fine said.

“When data comes at it, it is steered to SLC for the best performance in writes,” he said. “The data is then moved to MLC flash, as the read performance of MLC is on par with SLC. It’s unique. No one else has it.”

He gave the example of an all-flash Compellent array with six SLC SSDs and six MLC SSDs providing 12-TB capacity at a cost of about $180,000. To get 12 TB of high-performance disk storage, a company would have to purchase 82 146-GB 15,000-rpm hard drives for a total cost of $229,000.
