Peeling Of The Scrotom Skin

Summary

Jason Boche has published this network diagram in VI3, shows exactly which ports using VC, ESX and other services. I find it extremely useful to solve network problems on VI3. Here it is:




Happy New Year !!!!!! All the best for 2009 to arrive.

How To Wear Suspender High Waisted Pants

VI3 Networking in Internet Protocol Command

I know that with this title I can appear on all browsers, but always "internet" and "balls" are two terms that have been linked. ;-)
addition is rare not to talk about something technical, but it is Friday and the truth is, so I try to include a video blog, so we make an exception: ;-)

The Miraikan Museum, museum science from Tokyo, is a machine that is running a packet-oriented protocol (like TCP / IP) mechanically.

bits are black or white balls and data cables are tracks where the balls roll. There are also routers and PCs! Only the Japs can do something. The truth is that in college in the subject of networks, is what would have to put the first day!:

How To Wire Alpine Swr1242d

ball dmidecode: o View settings of memory DIMMs in your ESX and more

I found myself in the position to expand the memory of my ESX or just buy more servers (or a mixture of both).
But how many DIMMs have occupied my ESX?
(And in general: How do I know what memory configuration has my Linux servers?)

the first thing that can be used is applications of manufacturer, type Open Manage DELL or IBM Director or IBM DSA to see how many slot / free memory banks and therefore we have as we expand. This is a slower but more beautiful graphically. (Of course, these applications require installation of getting off to RedHat3 version, which is leading the SOC. It is possible that not what we seek to give a quick look at the configuration of memory that we have).

The second is to use a command (although I have not tested yet): lshw .
The trouble is that this command is ignored by default in ESX elos and suffers from the same as the first option: You have to install anything on the console of our ESX and I like to avoid it whenever I can.


Finally, there is a very useful command that did not know: It dmidecode (run as root) gives us a pile after pile of information from our hardware, including alia: BIOS Information, System Information, Base Board Information, Chassis Information, Cache Information, Information Processor, Port Connector Information: USB, Video, IDE / Parallel ATA, SAS, Serial, Ethernet, ServeRAID Adapter, PCI-Express / X Riser, Power Supply, Fan, PCI-Express occupied and free ... and much more ...

The information we seek (Structure of RAM DIMMs currently installed on the system) appears as follows:
 
Handle 0x004A DMI type
16, 15 bytes.
Physical Memory
Array Location: System Board Or Motherboard
Use: System Memory
Maximum Capacity: 65024 MB
Number Of Devices: 12
Handle 0x004B
DMI type 17, 27 bytes.
Memory Device
Size: 512 MB
Form Factor: DIMM
Set: 1
Locator: DIMM 1
Bank Locator: Bank 1
Speed: 266 MHz (3.8 ns)

Handle 0x004C
DMI type 17, 27 bytes.
Memory Device
Size: 512 MB
Form Factor: DIMM
Set: 3
Locator: DIMM 4
Bank Locator: Bank 1
Speed: 266 MHz (3.8 ns)
...
Handle 0x004F
DMI type 17, 27 bytes.
Memory Device
Size: 2048 MB
Form Factor: DIMM
Set: 3
Locator: DIMM 3
Bank Locator: Bank 5
Speed: 266 MHz (3.8 ns)

Handle 0x0055
DMI type 17, 27 bytes.
Memory Device
Size: No Module Installed
Form Factor: DIMM
Set: 4
Locator: DIMM 9
Bank Locator: Bank 6
Speed: 266 MHz (3.8 ns)



can see, there are 12 slots in total, some occupied by 512MB of RAM 2GB others, other free etc, etc. ..

Why Wont My Roms Work

PuTTY Connection Manager Posts

recently talking to an Oracle guru discovered this wonderful tool: PuTTY Connection Manager . Stands in for the lack of tabs and organization to which you get when you have a lot of windows open PuTTY. I personally prefer SecureCRT gives you basic, but you need a license. Therefore, when I use PuTTY, this has become programilla a indipensable.

Tombstone Quotes Halloween



Well, I have been a significant delay in publication of posts because I've gone a bit busy this last month. I put the posts in which I am working and I hope will be inmininte publication:
  • More about VMware HA in ESX Networking
  • Backup Host: ESX, ESXi
  • The damn clock in linux VMs
  • The scheduler, vCPUs and other relatives. Disaster Recovery
will gradually rising. I hope that by 31 all!
