SSD vs HDD RAID in Servers and Storage

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

ion miniSERVER

Most “server” deployments deserve a rich, robust server platform with redundant power, redundant cooling, redundant storage, multiple network paths and error-correcting memory, but many servers already have redundant applications and redundant data.  In some of these deployments it then becomes reasonable to consider a small, cool, low-power alternative approach with redundant storage and two network interfaces for redundant communications. ion calls that a miniSERVER.

ion SR70mach5 SpeedServer™

The new performance-optimized SSD-RAID Server from ION Computer Systems® is also price-optimized.  Based on ION’s award winning SR-71mach5 SpeedServer family and technology, the SR-70mach5 SpeedServer™ is a 1U rackmount server with optimized RAID and Standard Endurance SSDs. The SR-70mach5 SpeedServer is based on an Intel® ServerBoard and comes with (2) 3.4GHz 8-core Intel® Xeon® V4 processors, 9TB RAID 5 usable with Intel® DC SSDs Continue reading ion SR70mach5 SpeedServer™

Thin Provisioning: Nondeterministic Storage Feature #2

Much of modern storage management focuses on efficient use and allocation of storage capacity.  “Thin provisioning” is a primary mechanism for this, allocating just enough space to match each consumer‘s current needs, while promising more capacity when needed.  Thin provisioning is an effective tool for allocation of storage capacity.  When latency, bandwidth and IOPS are more important, thin provisioning makes these performance results nondeterministic.  Continue reading Thin Provisioning: Nondeterministic Storage Feature #2

SR-71mach5 SpeedServer

ION recently launched it’s flagship SR-71mach5 SpeedServer™ which continues to deliver on the SR-71 legacy of all-SSD storage for “disk-impossible performance”.  This new server incorporates new technology throughout yielding more processor cores, more and faster memory and much more random I/O performance. Standard processors in the “mach5” are two 12-core 2.6GHz Intel® Xeon® E5-2690 V3, but the full Xeon E5-2600V3 processor lineup is available.  Continue reading SR-71mach5 SpeedServer

SSD Performance has System-wide Effects

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
