Intel IoT Gateway Solution
What is Intel IoT Gateway solution?
It combines hardware and software benefit as a total solution, included connectivity, security and manageability.
Intelligent gateways collect sensor data at the network edge, then act as a filter to analyze and normalize the data for sharing through the network and into the cloud. Intel has developed a family of gateway solutions that enables connectivity between new and legacy devices by integrating technologies for networking, embedded control, enterprise-grade security, and manageability.
Intel® IoT Gateway development kits help you quickly develop, prototype, and deploy intelligent gateways. The kits also maintain interoperability between new intelligent infrastructure and legacy systems, including sensors and datacenter servers.
The kits include pre-integrated and pre-validated hardware and software from Intel, McAfee, and Wind River, helping you reduce time-to-market and development costs.
Intel® IoT Gateway development kit features
1)Standards-based interfaces for I/O, cellular, and Wi-Fi simplify communications down to sensors and controllers and up to datacenters and the cloud.
2)McAfee Embedded Control* maximizes security by dynamically monitoring and managing whitelists.
3)Wind River Intelligent Device Platform* XT and Wind River Workbench* provide a proven development environment.
4)Kits are complete with fully-configured compute board, wireless communications, security software, operating system, development tools, chassis, power supply, antennas, and documentation.

Want to add a cron into ESXi?
Recently our IT have one requirement to let ESXi automatic shutdown.
I do some study, and write a very simple script to finish this task.
Step1:
Add one script file in /bin/cshutdown.sh
The content is as follow.
#!/bin/ash
VMLIST=/tmp/vms
/bin/vim-cmd vmsvc/getallvms |awk '{print $1}' > /tmp/vms
while read VMID; do
if [[ $VMID == "Vmid" ]]; then
echo "Not a valid VMID"
else
/bin/vim-cmd vmsvc/power.shutdown ${VMID}
fi
done < ${VMLIST}
#Wait for 2 mins time for VM shutdown
sleep 120
busybox halt
Step2
Add this script into /var/spool/cron/crontabs/root
The content is below
30 20 12 12 * /bin/cshutdown.sh
The time format must be used UTC timezone, since VMware KB suggest don't suggest to use local timezone, so you must convert your localtime to UTC time.
Step3
Do following command to restart cron daemon
#kill `cat /var/run/crond.pid`
#busybox crond
This script still need to improve to double check the VM status is already shutdown well.
Maybe add this feature into next version.

Distance vMotion = Stretched Cluster? - blog.scottlowe.org - The weblog of an IT pro specializing in virtualization, storage, and servers
Long distance vMotion still need Layer 2 environment.
If the long distance site is using different IP subnet, it could use MPLS to extend them as one Layer 2 network. It is too difficult for me to implement such kind of environment.

RedHat still insist to open their source in Cloud area, and call others(Google, Amazon) to join this.
PS: Always see BMC appearing in cloud platform anywhere.
