Nexsan takes the lead in the enterprise layer based on 3TB SATA hard disk of pushing away and stores
China end storage system manufacturer Nexsan claims oneself is the first manufacturer using 3TB SATA hard disk in storage system of enterprise layer.
This kind of memory density makes the available capacity of 1U high memory cell in the array can be improved to 45TB, this achievable kind of memory density that there is no second manufacturer to claim at present.
According to informal news, EMC Iomega will introduce desk-top apparatus and framework type array of 3TB HDD soon too, the capacity of monolithic hard disk of maximum is 3TB at present, it is estimated other manufacturers will announce their 3TB products quickly too.
Nexsan lying in California a thousand rubber cities shows it has already put out the E series storage system using 3TB SATA hard disk to construct, namely earlier 4U Nexsan E60 storage system put out of this quarter, from this week, all Nexsan E systems can choose to use the new 3TB SATA hard disk to store the products, including E18 and E60X.
Nexsan says its series E have offered an extensible high density high performance platform, all E series storage systems have centre that store the management software, make the management role simpler.
The storage system of the enterprise layer includes being high-reliability too, such characteristics as low power consumption and space are taken up small.
Switzerland stores Storage Switzerland. The chief analyst George Grump says: “Such lateral memory density and energy saving index are impressive, has set up big obstacle for other storage system manufacturers, as the forerunner introducing these innovation in density and power management to the market initially, the execution ability of project group and company of Nexsan should be praised ” .
The Nexsan E series storage system is available soon, use 3TB SATA hard disk, E60 trigger price of the single control device is 80000 dollars.

Atlantis brand-new solution breaks through VDI I/O bottleneck
One is called ” Atlantis ” Atlantis Company last treatment fracture I/O the solutions brand-news of bottleneck problem VDI a few days ago: Measure and delete empty I/Os on NTFS rank.
ILIO 2.0 of Atlantis ILIO mean the ordered image is optimized It is his hardware device’s software that behaves, it can run on fictitious tabletop Vmware and Citrix as a virtual device. As everyone knows, a large number of fictitious desk-top I/O may make the storage array collapse, make the quantity of hard disk of the array go beyond the quantity of the capacity demand, the purpose, just in order to let I/O ability achieve the appropriate level. This too causes the storage array to use the hard disk of the solid condition and according to the reason why that way calculates I/O ability of them.
Atlantis fits, because go on in NTFS agreement grade, it can optimize Windows XP and connect the influence way between VDI storage array with Windows7 and. Atlantis fits, it can also repeat the data and delete dealing with to them in all VDI images before reaching the storage equipment, thus reduce the highest memory demand of 90% Windows image assembly effectively and further reduce VDI to dispose the memory capacity with required scheme.
Can reduce the fictitious desk-top cost to the cost of physical PC with software integration. Atlantis ILIO can be through reducing the plentiful used storage equipment by 20 times and offering and storing and selecting more, such as utilizing low-cost SAN, NAS or local magnetic disc,etc., thus reduce VDI cost of investment by 75% at most.
Claim in Atlantis, if the fictitious tabletop that operates has antivirus software, then the fictitious desk-top quantity that a server can deposit will be reduced by half. It has proposed a kind of solution to this too, that is to use McAfee MOVE AV. Atlantis to claim: “Atlantis ILIO and McAfee MOVE AV corollary use can improve the memory density by one time, and the characteristic should be superior to physical PC, can reduce the carrying cost by about 90% at the same time. ”
The new solution that it puts forward seems good. An organization named 451 Group leaves such a comment on the websites of Atlantis:
ILIO understands Microsoft’s Windows series operating system. These operating systems considered advantage and inferior position of the traditional PC during design. They assume that there is a specialized local magnetic disc of low dead time that is for them to use. Depositing the fictitious tabletop utilizes expensive long-range memory to replace the low priced here and store. The result causes users, the application software to launch fighting for with the tabletop for definite I/O capacity resources. Windows system does not know what a problem of dealing with above-mentioned resource fighting for and performance reduction.
ILIO apparatus can change the request order of Windows, let Windows think it was a local magnetic disc, but ILIO knew a minidisk actually in SAN of its. Intellectual cache is combined with image management, ILIO apparatus own memory capacity can meet most demands, at all on the issue that will not store I/O bottleneck. ILIO should improve the fictitious desk-top characteristic, reduces SAN apparatus floor space at the same time, simplify central video patch and staging to operate.
If is really so, this means you can use general SAN or NAS storage equipment and obtain with Hewlett-Packard 3PAR SAN or EMC VMAX uniform characteristic. Alternatively, you can also match and use ILIO with 3PAR or EMC array, improve a little more VDI capacity. This is worth trying.

Single disc 1TB! Samsung shows first 4TB hard disks in the world
Though CeBIT 2011 exhibition has already been concluded, exhibits are really numerous, the thing of a lot of heavyweight is getting forgotten, wait for us to excavate slowly, for example not know until we today, Samsung has already shown the high hard disk up to 4TB of first section of capacity in the world quietly.
The existing top products of not merely total capacity ratio have increased by 1/3, Samsung, the intersection of SpinPoint EcoGreen F6 and the intersection of 4TB and hard disk adopt most advanced 4 dish put and design also, that is to say the single disc capacity rises to 1TB, have increased by 1/3 than 667GB before this. It may have used the sixth generation of vertical recording memory technology, the memory density has 630Gb each sq. in. at least.
This just means, we could saw single disc 1TB and hard disk of the double-disc 2TB.
The production code number of Samsung this 4TB hard disk is HN-D201RAE, interface SATA 6Gbps, buffer 32MB, rotational speed 5200RPM the energy-conserving series of green ,Release time and has not revealed specifically, but confirm intending to put out within this year.
In fact many insiders expect to see the birth of single disc 1TB technical maturity and 4TB hard disk this year at the end of last year, have not just thought of realizing so soon. With the break-through of 2.2TB capacity obstacle, the popularization of 3TB, 4TB will not be very remote either. Who says the mechanical hard disk stagnates?
