AES NI Acceleration

Intel Core i7 5960X / 5930K / 5820K Haswell-E review: 8 cores at last
1. Tested AES-NI Acceleration in Intel CPU can give ~5.3 times boost in AES
2. Tested AES-NI Acceleration in AMD CPU can give 3.8-4 times boost

General

Maintenance

SQL Command to show table disk usage:

```

ALTER DATABASE WhatsUp SET RECOVERY SIMPLE;
DBCC SHRINKDATABASE (WhatsUp, 10);
DBCC SHRINKFILE (WhatsUp, 10);
DBCC SHRINKFILE (WhatsUp_log, 1);
ALTER DATABASE WhatsUp SET RECOVERY FULL;

Active Script Action

Idea: although can use script to change device status, it must have way to check how a device is up again. (e.g. should have a resume normal Passive Monitor)
Moreover, it may confuse if multiple device status are received. (if the multiple down status were triggered by Passive Monitor, it don’t know when is really called “resume normal" – multiple resume passive monitor update? Or only 1 resume passive monitor update?)
To have Context.GetProperty(“DisplayName") supported for Active Script Monitor
DeviceID can be obtained by the general Context object with: Context.GetProperty(“DeviceID")
Trigger device maintenance mode automatically
Use script function EventHelper.SendChangeEvent to change the device status by a certain event
Using Powershell to update the state (send state change event) of a device
Example to use PowerShell to call the SendChangeEvent function (require to use the 32bit PowerShell)

CPU Ready Time in VMware and How to Interpret its Real Meaning
- in ms, more core/vCPU will have higher CPU Ready Time
- per vCPU, >5% is warning, >10% is critical (each vCPU count 100%, 4 vCPU = 400%)
- host over subscription can affect this counter
- ([CPU Ready ms value] / (20s * 1000)) * 100 = CPU Ready % value
  - 1000ms = 5%
  - 2000ms = 10%
  - 20s is based on the graph’s default: (refreshes every 20 seconds)
