New storage from Sun: J4200/4400/4500 and X4540 Storage Server
Sun announced some new storage components today: At first we announced the J4200 and J4400 disk arrays. They are JBOD´s, just bunches of disks. The J4200 has up to 12 SAS or SATA disks in a 2 RU enclosure.
The new J4400 is a 4 RU enclosure with 24 SAS or SATA disks. It´s a doubled up version of the J4200:
Well … and then there is the J4500. As the name suggests, it´s a JBOD that looks really similar to the X4500 - the Thumper - and it has similar characteristics: 48 harddisks on 4 rack units.
When you look at the rear side of the J4500 you will not see the Opteron based System controller. Instead of this you see an interface board with four SAS-connectors. Two of them are host connect ports. The other two are used to stack J4500 enclosures together.
And last but not least there is the X4540. It´s our new storage server. It looks almost as the old one. The changes are internal ones. The system now uses quad-core chips instead of dual-cores, the system gives you 3 PCI Express slots instead of the PCI-X slots of the old system. The new X4540 has a slot for a compact-flash card to boot the operating system. Or to say it more shortly: We integrated the stuff our customers wanted to see in the next-gen thumper.
