以前就超喜欢电吉他,Santana无疑是我的钟爱。上个星期终于拿到了他的2007精选“ultimate santana”,喜欢得不得了。尤其是其中的“europa”, 完全是吉他配合有力的鼓乐,尽情的体会由闲散到积郁到爆发的畅快!我喜欢强大的鼓乐给与全身的震撼,配合电吉他超强穿透力的高音直接敲击耳轮最敏感的部位!

Architects in IT
Architect is one of the most confusing role in IT. I studied the following architect in IT and hope it helps clarify. My understandings are:
- Engineer fixes the problem with instructions and manual;
- Analyst provides the solutions with business owner;
- Architect draw high-level plan to prevent issues/problems for the future.
Set maximum LUNs for ESX server 3.0
VMware only scans for the first 256 LUNs (0–255). If your SAN zone
contains LUN IDs that are higher than 255, follow the instructions in
the VMware SAN Configuration Guide to change DiskMaxLUN to the value you need (available from http:/www.vmware.com/support/pubs/vi_pubs.html). Make sure to run cos-rescan.sh to make the LUNs available to the VMware Service Console without rebooting the system.
One known issue on EMC ECC
After we migrate the ECC from old server to new server and rediscover the storage and monitored devices, we realized the storageScope can not display the historical data before the migration date.
EMC storageScope known issue fixed by me
After we migrate the EMC SAN storage to a new SAN device, we found the storageScope graph does not work properly. It can either show the historical data till the migration date, or show the graph from migration date to now. This means the graph is cut at the migration date.
Tape devices unavailable after device reset

Allocate storage from SAN to host (step by step)
Comparing with allocating space from local disks, it is quite tedious for allocating SAN storage to SAN-attached storage. This is a simple step-by-step guild of doing so with EMC Control Center for Solaris environment.
