SAS disk array Aerospace Joint log al-7121a to build SMB storage scheme

How to spend a limited amount of money on a more cost-effective storage product is the most vexing problem for the small and medium-sized enterprises that are currently growing in storage demand. In the storage disk array, with the upcoming launch of the 6Gbps SAS standard, in the storage market this unique transition period, in the maturity of 3Gbps SAS related products, but gradually showed a trend of trends, and has become a large number of small and medium-sized enterprises most concerned about cost-effective products.

As a number of government agencies and industry organizations selected SAS disk array products, aerospace joint volunteer Research and development of AL-7121A, with high security, high-performance, high expansion and many other advantages, as a small and medium-sized enterprises to create low-cost storage solutions of the popular SAS disk array products.

Superior Performance Farewell bottleneck

As enterprise storage, the biggest problem is how to solve the bottleneck in data transmission, which is the main reason why users value host interface. In this respect, SAS undoubtedly has the innate advantage. Sas-sas model is equipped with small block (512Bytes) or even large blocks (128KB or more) storage, comparable to the data throughput of FC devices, and the aerospace joint log al-7121a is such a typical Sas-sas model.

AL-7121A has two SAS host interface and 4 mini SAS Interface (support 3 SAS expansion cabinets), convenient for users to the new and old interface compatible, but also has the SAS interface al-7121a, the actual reading speed can achieve amazing 600mb/s. Inside the mainframe, AL-7121A supports up to 12 blocks of 3.5-inch SAS or Sataⅱ hard drives. From the inside to the outside, AL-7121A enables SAS storage products to be fully functioning with high-performance and highly flexible features.

In order to ensure high-performance performance, the Aerospace joint log al-7121a using AMCC PowerPC 440SP ASIC CPU, and this CPU not only has a powerful hardware engine also built-in memory controller, Allows al-7121a memory to have a more flexible range of choices from 1GB to 4GB capacity. The RAID 5 and RAID 6 hardware acceleration performance is also significantly enhanced.

Supported by RAID capabilities, AL-7121A's support for RAID is quite comprehensive, supporting not only the common raid levels of 0, 1, 3, 5,10, 6, 60,nraid, but also the current very popular JBOD to ensure that different enterprises, Different businesses offer a wide range of applications and performance-intensive storage services.

Soft and soft, safe and reliable

Whether the product is safe and reliable is extremely important in storage devices, and the al-7121a not only utilizes a rich RAID level to achieve multiple data redundancy. At the same time, it also supports disk Self Test, disk scrubbing, disk clone and other technologies, and integrates the array Recovery Utility (ARU) tool to ensure the maximum security of the data.

Of course, if the disk array has a hardware problem, the aerospace joint log al-7121a can also be the first time to use LCD indicators, built-in buzzer, or email and SNMP and many other prompts function for automatic alarm. If there is an end-to-end I/O path failure, host-based Pathguard software also enables fast switching and recovery, and quickly restores data loss due to hard disk damage through built-in automatic data reconstruction.

On the management side, the AL-7121A uses a Web browser-managed GUI to make it easier to configure and monitor the system-wide state through a simple and clear interface. At the same time telnet, SSH remote control support, but also for the management and maintenance of enterprise administrators to provide the greatest convenience.

In the hardware reliability of the aerospace union al-7121a also very good. Mainframe dual Flash ROM, and built-in flash automatic backup function, to ensure that firmware even in the upgrade or one of the flash ROM damage or failure, the system can still be safely and reliably run. Dual 350 watt power supply design, not only can greatly improve the system's safe running time, hot-swappable design also allows enterprises to use without shutting down the power to complete the replacement of the problem.

Create lower-cost storage

With excellent performance and security, the aerospace al-7121a has a wider range of applications, and the biggest attraction for small and midsize enterprises is the possibility of creating low-cost storage solutions for SMEs.

According to IDC estimates, the capacity demand of many enterprises is about 50% annual growth rate, and the growth of capacity demand will inevitably let the enterprise to the original storage products of the hard disk to increase or upgrade. On the al-7121a, the enterprise chooses to install the SAS hard drive or SATA hard drive according to its application demand and budget, even can mix assemble. This is undoubtedly of great appeal to small and medium-sized enterprises, which are trying to control their budgets and pursue the lowest possible means of capital storage.

Of course, the price of the product is the focus of small and medium-sized enterprises on the aerospace al-7121a, which is another advantage of al-7121a to create low-cost storage solutions. Since the new standard 6Gbps SAS has been touted by many storage vendors, it has also attracted more users to look at it. However, the original 3Gbps SAS will not be replaced in the short term. Unlike home PCs and other devices "overnight", the special needs of the storage products require the gradual change of the whole ecological environment, which means that the transition period is longer. According to IDC Data 3Gbps SAs are really going to be completely replaced by 6Gbps SAS at least until 2011. It is based on this reason the original standard 3Gbps SAS is not dead, but because of the advent of 6Gbps SAS, so that it reached the most cost-effective and competitive period.

In addition, the new 6Gb SAS with Multiplexing (multiplexing) technology also allows users of the currently-purchased 3Gbps products to avoid the emergence of repetitive investments. SAS ecosystem supporters, including OEM vendors, motherboard suppliers and semiconductor providers, are also being prepared to push compatible with existing 1.5Gbps SATA, 3Gbps sas/sata products and products with 6Gbps SAS infrastructure. This also makes the purchase of 3Gbps SAS products More assured users, completely avoid the upgrade due to the waste of resources, is undoubtedly for small and medium-sized enterprises to bring another gospel.

The need for sustained growth in storage capacity in small and medium-sized enterprises is enormous, and typical small and medium-sized enterprises face the dilemma of how to manage and protect all data without increasing the number of employees. The al-7121a configuration is simple, easy to manage, scalable, with the primary storage management functions, such as multipath redundancy, data replication functions, fully meet the storage needs of small and medium-sized enterprises, coupled with the increasingly outstanding cost-performance advantages, the aerospace joint records al-7121a is undoubtedly the best small and medium-sized disk array storage products choice.
