E2128J      
SAS & SATA JBOD
Multi-purposes Disk Enclosure
 
 
Overview
The E2128J is the most versatile SAS/SATA II disk enclosure system, ideal for mid-range and high capacity storage application environments. Based on 3Gb SAS host interface, the E2128J supports the choice of SAS (Serial Attached SCSI) and/or SATA II (Serial ATA) disk configurations. It is capable to deliver a system bandwidth of up to 1200MB/sec.
 
 
 
Simply put, there is no Competitors out there for the same Features, Price, and Qualify that gets near what the E2128J can offer !
 
 
Features & Benefits

Cable-less & Modular Design

Cable-less backplane and SAS Expander IO module guarantees maximum data singal integrity, eliminating potential troubles by cable-wiring, easy to service and maintain.

 

 

 

Staggering Spin Up

Built-in staggering spin-up for hard disks at power up. The

feature extends the life/duty cycle of the hard disks and

power supply.

 

 

LCD Display & Enclosure ID

Includes LCD to display critical information of the enclosure. Also, the LCD shows the ID of the enclosure, so that in a multiple enclosures environment, when the RAID management console tells which enclosure has drive failure, you know exactly which enclosure to go to.

 

 

 

 

SES Enclosure Management

Utilizes industry-standard SCSI Enclosure Services (SES)

to monitor enclousre and disk status and conditions, and

communicate with host RAID adapter to report those info from within the host RAID management console.

 

 

 

  PHY Zoning

 Zoning(aka PHY Zoning) is to divide up 12 disks into 2 groups, each IN-Port allows access to one group without interference to the other group. So two RAID controllers can share the same JBOD with each has its own group of disks to create RAID volume over SATA disks without the expensive interposer/MUX boards. This feature is typically useful for two types of applications: two computers share the same JBOD or one computer aggregating 2 RAID controllers for maximum throughput.

 

 

 

 

Multi-purposes

Supports both SAS (Serial SCSI) disks and/or SATA II disks to meet the requirements of different applications with different price/performance characteristics. Cost-effective SATA drives can be used for capacity oriented storage application such as disk-to-disk backup, data-archiving, or digital video editing.

Enterprise level SAS drives can be used for I/O intensive apllications including transactional database.

 

 

Craftsmanship

Compact 2U x 12 Bay with very short depth (18.12"), Buit with  strong metal material, and excellent cooling without noise

 

 

 

Scalability

Built-in SAS Expander for 12 disks inside the enclosure.

Supports up to 4 enclousres chained together for capacity expansion

 Wide Range RAID Adapters Support 

Compatible with most of the brand names SAS RAID adapters available in the market: Areca, LSI, Intel, Adaptec, Dell, 3Ware, and ATTO.
