Disk I/O slows the system, especially when overloaded with requests competing for CPU processing. Create fair and smart system balance by controlling device I/O bandwidth monopolizers.

Better Control

User processes that monopolize device I/O cripple server performance and affect all system customers. prevent this with individual and group limits for users, programs, devices, and mount points (like NFS, iSCSI, and more).


Better Efficiency

Prevent I/O storms and smooth out the I/O scheduler’s workload without the waste created by static limits. What if some users consume below their allocated share of I/O bandwidth, creating a total system surplus? BetterIO rapidly and incrementally “auto-scales,” or distributes surplus resources to remaining system users. Auto-scaling is based on highly-configurable conditions and use ranges as well as recent user activity.

Better Density

More users per server usually means higher risk of overuse and instability. But now you can prevent I/O traffic jams and overconsumption with smart I/O limits. Multiply your server population with control and predictability.

Better Monitoring

Sortable columns present real-time, per-user data on bytes, calls, and processes along with all commands and their device of origin (vda, sda, etc.). You can also see useful totals like read/write quantities in bytes, the number of read/write calls, and total throttle data with usernames and PIDs.

Better Profit Margins

Over-consuming I/O users often make it necessary to buy more servers or reduce the number of users per host to lessen per-server chances of over-use. These options cut profits. But with BetterIO’s definable boundaries on I/O bandwidth and operations per user, more users and virtualized systems can share a given amount of bandwidth, reducing costly hardware additions and cuts in tenants per server. You may also save money in reduced power consumption and diminished data center heat.

Easier System Administration

You can define all settings in one configuration file so the same file can be used on any system without changes.
