Welcome to FTP mirror.garr.it service.
GARR is funding an ftp-mirror archive. The overall capacity is now about 27 Terabytes total, distributed in two locations of its network.
The architecture includes two different SANs for the two sites hosting the mirror servers:
Milano site: Two Raidtec's FibreArray eXtreme SAN Storage Arrays (16 hot swappable FC disks of 146Gbyte each). This SAN is connected to mirror3.mirror.garr.it.
Roma site: February 2010: the old JBOD was substited with a new one with 26 x 1TB SATA-II disk.
Until February 2010: Xyratex JBOD 48, with 48 x 500Gbyte SATA-II disks, for a total of about 24Terabyte. Two servers are connected through two distinct FC RAID controllers, with double FC host NIC to enhance availability: mirror1.mirror.garr.it, mirror2.mirror.garr.it.
The service is opened to 350 ftp users ,
300-500 http requests each, in the current configuration:
-
Three Dell PowerEdge 1950 with two quad Xeon CPUs 32GByte RAM, two 10/100/1000Mbps Ethernet interfaces.
-
Two Raidtec's FibreArray eXtreme 3002 SAN Storage Arrays (16x146G disks)
-
One Xyratex 4835 FC to SATA-II SBOD (48x500G disks), two controllers RAID T2000
-
One DELL PowerEdge 2850 Intel Xeon 3.4Ghz 2M L2 cache, 2Gbyte RAM, 3*73G 10Krpm SCSI Ultra 320 as web server machine for
GARR mirror services.
Various aspects of the service are monitored:
