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→
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→
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.

Or, How Many Eggs in One Basket? Huge storage systems are available today supporting large numbers of disks, allowing the creation of massive storage resources. Storage Servers and storage enclosures suporting up to (60) 3.5″ disk drives are now common. Filling those bays with 6TB disks yields a system with 360TB raw capacity – one third of a petabyte! That is now an easy Continue reading Storage Sizing for Capacity and Performance→
