Advanced Technology for Maximum Performance


 

Enterprise Storage Stack (ESS)


WildFire's Enterprise Storage Stack (ESS) is software which lets integrators and skilled users build extremely fast Enterprise grade, all-Flash storage appliances and local storage at costs vastly below a dollar a gigabyte.

WildFire ESS achieves its tremendous speed through conversion of clusters of random writes into a memory mapped continuous linear stream. Writing all data linearly results in random write speeds that are typically ten times faster than standard Raid-10 and eighty times faster than Raid-5 or Raid-6. When computational resources are sufficient, ESS write rates typically match the composite linear write rate of the SSD pool.

Superior IOPS speed: ESS can internally generate as much as 2,000,000 4KB random write IOPS with 24 SSDs.  Externally, ESS will deliver 300,000 4KB random reads or writes over a 10gigE connection from an array of 8 or more SSDs configured RAID-5 or RAID-6.  Greater external levels are possible with more SSDs, network connections, and targets.  Most all-flash RAID-5 solutions will only deliver 20,000 to 30,000 write IOPS. RAID-10 solutions typically deliver only 100,000 to 150,000 write IOPS with 24 SSDs.  Low write IOPS will radically slow down the total throughput of the system because time consumed by writes is not available for reads.

Superior large record transfers. ESS will also deliver large amounts of data.  For instance, a 24 SSD system managed by ESS will deliver almost 6GB a second through a single 40gigE port read or write, and can deliver a lot more with multiple ports and cards. With multiple interfaces, write speeds will approach 11GB/sec.  NVMe can also be used to increase write speeds.

Superior single-job speed.  While ESS cannot increase the random read speed of SSDs, it random writes single thread at very high random write speeds.  Tests show that with 24 SSDs, ESS based systems will internally single-thread random write 4KB blocks at 250,000 IOPS (1GB/sec) and will write 1MB blocks at 4.8GB/sec.  Single thread throughput greatly affects the time needed to perform all manner of big jobs, be these report generation or 4KB video rendering. Few all-Flash storage appliances can demonstrate such performance. This performance gain is true no matter the grade of SSD you are running:  Consumer, Read Intensive, Data Center, and Enterprise grades of SSDs will all read and write faster when managed by ESS.

 

 

Profound write reduction and life enhancement.  ESS dramatically reduces write amplification.  Accordingly, less expensive Consumer  or Read Intensive SSDs managed by ESS will typically last ten to forty times longer, and will be capable of a daily overwrite of all data.  But even Data Center and Enterprise SSDs will see significant life extension with ESS because many of the techniques used by ESS to reduce write amplification, such as RAID stripe alignment and compression increase the useful life of all SSDs.

Profound cost reduction.  ESS lets you use less expensive Consumer and Read Intensive SSDs while achieving or exceeding the effective data updates of Data Center media.  Because it performs best in a RAID-5 or RAID-6 environment, ESS also lets you use fewer SSDs.  The combination of these can reduce the SSD cost per usable gigabyte by as much as 75%.

Larger systems.  Because ESS requires fewer SSDs for a given unit of usable storage, and because ESS will make inherently-more-dense Consumer and Read Intensive SSDs work with higher durability, ESS-based systems can be much larger than traditional RAID-10 systems.  ESS based systems can employ up to 48 7.68TB SSDs, and can address up to 256TB of usable space.

Affordable softwear cost.  ESS costs a small fraction of the SSD costs it reduces.  When significant cost reduction is combined with superior speed, durability, scale, and reliability, ESS generates exceptional value.
