5. Fabric infrastructure of BeiJing-Lcg2

6.  Core Server( SRM-dcache, CE, TOP-BDII, RB, LFC, Myproxy, MON, VOBOX )  IBM-X3650 (SRM-dcache, TOP-BDII,RB, LFC, Myproxy, MON, VOBOX,UI) (totally 9)  CPU intel 5130 X 2  2X2GB RAM  2X73G SAS 10k Disk Raid1  1Gb network.  HP DL380 G5 ( CE-Torque, DPM-SE, DPM-Disk,DPM-database) (totally 10)  CPU intel 5420 X 2  4X4GB RAM  2X146G SAS 10k Disk Raid1  1Gb world network. 10Gb local network  Worknodes(50 WNs)( The cpus(cores) is 408 now )  Dell M1000e Blasd server  CPU intel 5430X2  4X4GB RAM  1GB network

7. Fabric infrastructure of BeiJing-Lcg2  Storage Element(dcache)  3 head node + 2 poolnode + 4 disk array  total amount of space is 40TB  Storage Element(DPM)  2 head node + 8 poolnode + 16 disk array  total amount of space is 160TB  Computing Element  Ths cpus(cores) is 408 now.

8. Grid-service of Beijing-lcg2

9. middleware  Almost all the core service han been update to SLC47 glite-3.1.  Now CE, SE_dcache, WN, UI, BDII, MON, LFC running on slc47 and glite-3.1.  RB,running on slc308 and glite-3.0, These service will be update to new version ASAP.

10. Dcache Storage Element system  We established a new central Dcache Storage Element which replace the old atlasse01 and cmsse01.  New SE running on slc45 and glite-3.1.  Dcache version is dcache-server-1.8.0, it support new version of SRM v2.2.  New SE have 3 headnode some poolnode.  Now the total amount of space is 20TB.
