ion SR-71mach6 adds Enthusiast-series Optane™ drive options

Posted on by — No Comments ↓

ion has added a new option to its SR-71mach6 SpeedServer™ Configurator to allow the selection of Intel® Optane™ SSDs from the 905P Enthusiast series. Compared to Intel’s Optane DC P4800X series, this family continues to deliver an Uncorrectable Bit Error Rate (UBER) of 1 sector per 10^17 bits read but the endurance drops from an astounding 60 full drive writes per day to only Continue reading ion SR-71mach6 adds Enthusiast-series Optane™ drive options→

SSD vs HDD RAID in Servers and Storage

Posted on by — 2 Comments ↓

SSDs in servers deliver performance, whether measured in IOPS or GBps or latency, that is just plain impossible with disks. SSD capacity is now greater than that of performance disks. Price is the factor that still keeps many organizations away from deploying servers with SSD storage when the improved performance is not a significant benefit. The better reliability of SSD might be more important. Continue reading SSD vs HDD RAID in Servers and Storage→

Storage Capacity: TB vs TiB

Posted on by — No Comments ↓

For years, ion has reported usable capacity of disk and SSD storage in GiB and TiB instead of GB and TB. Why?  And what’s the difference?  Basically, 1 GB = 1,000,000,000 bytes while 1 GiB = 1,073,741,824 bytes. That is about 7%!  Look at ion‘s SR-71mach6 SpeedServer or PS StorageServer for examples of capacity reporting. You can learn more about the differences in the Continue reading Storage Capacity: TB vs TiB→

Observations on NVMe SSDs in Server Applications

Posted on by — No Comments ↓

2019 Update: Intel Xeon Scalable Processors have added significant support for NVMe SSDs.  We believe that these improvements make NVMe SSDs the high performance storage approach of choice, but have not yet been able to complete testing of that theory.  Our recommendations at this point are to use NVMe where performance matters.  And where the highest level of performance with the lowest possible latency Continue reading Observations on NVMe SSDs in Server Applications→

Disk-Impossible File Server

ION® Computer Systems, Inc. recently published benchmark results for its SR-71mach5 SpeedServer™ running Microsoft® Windows® Server 2012 R2 with the SMB 3.1 protocol.  Yes, the performance is “Disk-Impossible!”.  A single 2U “mach5” system costing under $80k served 64kB random reads at 10 Gigabytes per second and delivered 8kB random reads at 1 million Input/Output Operations per second.  Average latency as low as 1ms was Continue reading Disk-Impossible File Server→

SSD RAID

There are many opinions on the benefits and liabilities of SSD RAID floating around the Internet; ION’s experience with SSD RAID differs dramatically from some of it.  ION’s SR-71mach4 SpeedServer™ is a server and storage platform optimized for and with SSD RAID.  This article shares some observations on the performance and endurance of SSDs in RAID usage, and examines and compares performance in different Continue reading SSD RAID→

SSD Performance has System-wide Effects

Posted on by — No Comments ↓

The impact of SSDs on I/O related performance in a server is dramatic. Unleashed from the mechanical limitations of spinning disks, a single server can perform 10s or 100s of thousands of I/O Operations per second, IOPS, instead of just a few thousand.  Without long I/O waits, processor, RAM and RAID controllers can all get much busier, but the impact on humbler pieces of Continue reading SSD Performance has System-wide Effects→
