Dell Fluid Cache for SAN

Dell Fluid Cache for SAN

Dramatically accelerate your application performance

Slow transactions and application response times can hurt your business. Experience dramatic application acceleration with Dell Fluid Cache for SAN. Keeping both data writes and reads highly available with write-back caching, this solution provides the flexibility to quickly scale up cache pool resources — allowing your organization to meet the changing demands of enterprise application I/O.

Including this end-to-end solution in your current environment can enable you to:
  • Greatly reduce average response time (ART) of workloads such as online transaction processing (OLTP)
  • Effectively reduce your cost per virtual desktop in virtual desktop infrastructure (VDI) environments
  • Achieve faster database response times while keeping data stable and highly available
Dell Fluid Cache for SAN can supercharge applications requiring high data I/O such as:
  • OLTP on Oracle® databases
  • OLTP on Microsoft® SQL Server® databases running on VMware®
  • VDI on VMware
OLTP database benefits
  • Accelerate your applications — In a Dell lab test, ART jumped from 876 milliseconds (ms) to 6 ms1 when supercharged with the Dell Fluid Cache for SAN — a 99 percent improved response time.
  • Increase concurrent users — In the same test, the support for concurrent users surged from 2,200 to 14,000; a 6.4 times increase.
  • Regain confidence in your transactional data — Maintain confidence knowing that in the event of a compute node outage, write data is highly available and persistent in the cache pool cluster.
Virtualization benefits
  • Avoid hardware overprovisioning — Address usage spikes and avoid boot storm performance issues by quickly scaling your virtualized workloads on the fly using Dell Express Flash PCIe solid-state drives (SSDs).
  • Achieve a lower cost per desktop — Meet the performance needs of heavy and power virtual users while using economical storage options consisting of only rotating drives.
  • Deliver faster business results — Satisfy and grow your customer base by providing them with speedier data access in a virtualized Microsoft SQL environment.

Architecture Design Guidance
The flexibility of the Dell Fluid Cache for SAN solution provides deployment options to meet your specific workload needs.

Minimum architectures are ideal for OLTP customer relationship management (CRM) environments and normal-to-heavy VDI user types.

Maximum architectures are recommended for multi-OLTP systems (such as CRM and enterprise resource planning [ERP], and ecommerce) and heavy-to-power VDI user types.

How the solution works
Dell Fluid Cache for SAN is an end-to-end application acceleration solution, architected by combining:
  • Dell Fluid Cache for SAN software
  • Select Dell PowerEdge servers that support PCI Express Flash and internal PCIe SSD cards (Micron M420P SSD cards)
  • Dell Compellent storage
  • Select Dell Networking 10/40 GbE switches and Mellanox ConnectX-3 network adaptors
  • Dell support and deployment services
To deploy the solution, you need a minimum of three Dell PowerEdge servers containing Dell Express Flash PCIe SSDs, which are connected to Dell Compellent storage, and the establishment of a private cache 10/40 GbE network.

Licensing information
Dell makes the Dell Fluid Cache for SAN licensing simple for deployment. With licensing at the node level, you don’t need to worry about the size of your cache, CPU or sockets per server. Purchase a three-node cluster license for initial deployment and add nodes with expansion licenses as you need to scale performance for your applications.

Dell Fluid Cache for SAN is licensed as a perpetual licensed Dell software product. The following licensing options are available:
  • Evaluation license — 90-day free evaluation license of Dell Fluid Cache for SAN
  • Cluster license — Covers licenses for three Dell PowerEdge server nodes
  • Expansion license — Allows you to add one additional server node to your cluster license, up to eight total server nodes per cache pool
  • Annual software maintenance — Required at point of sale and optional thereafter
Customer experiences
Our customers are quickly discovering the advantages of the Dell Fluid Cache for SAN solution. See what they are saying:

Accelerate your virtual workloads
“The Dell Fluid Cache for SAN solution offers an impressive balance of performance and cost for virtual environments. So far, we’ve seen a 30 percent reduction in response time of our virtual environment and have experienced no downtime since the solution began running. And we estimate this solution would cost around half of what it would be to update the primary storage system with like amounts of high performing solid-state drives. If we need more data storage, we can simply add another node and make the cache pool bigger. This gives us a lot of flexibility without disrupting any applications.” — Daren Dugan, Virtualization Manager, University of North Texas System

Reduce database queries from hours to minutes
“The Dell Fluid Cache for SAN solution includes an intelligent caching system that accelerates reads and writes for a significant performance boost. In our SQL environment, a database query that previously ran for over an hour was completed in less than 15 minutes using Fluid Cache.” Peter Lonis, Solution Consultant, LeaseWeb

Step up your provisioning and performance
“Our team’s model is that of a service provider to the university system and our primary goal is to offer the best level of service possible to all our customers across the various UNT system campuses and organizations. We’ve had to step up our game, and the Dell Fluid Cache for SAN is another tool in our toolbox that helps us do that. To be able to offer this level of performance at such a reasonable cost is a huge advantage for us. Any organization or institution that has transactional types of data can benefit from the Dell Fluid Cache for SAN solution.” — Monty Slayton, IT Manager, University of North Texas System

Quickly improve enterprise resource planning (ERP) and I/O-intensive ecommerce experiences
“The Dell Fluid Cache for SAN solution can improve the way we do business by allowing our colleagues to spend less time waiting for our ERP system. More importantly, our customers with I/O-intensive ecommerce or ERP databases will deliver results quicker and have a better experience.” — Marc Burkels, Manager of Dedicated Hosting, LeaseWeb
