Server hard drive you know and don't know

The world has officially entered the ZB ERA in 2010, according to IDC estimates, by 2020 the world will have a total of 35ZB of data volume, compared to 2009, the volume of data will increase 44 times times. March 2012, the Obama administration unveiled a big data plan, the first batch announced investment 200 million dollars. The "Twelve-Five" project, published by the Ministry of Technology, puts forward information processing technologies as one of the 4 key technological innovation projects-we have, without a doubt, entered the "Big Data Age", and big data is affecting our lives, changing business and even government.

Where is this huge amount of data stored? How to manage, analyze, archive, obtain more value from it, become the problem that the enterprise faces urgent need to solve. For the individual, we can store the data in the U disk, mobile hard disk or notebook hard disk, or even personal cloud network disk; For enterprises, if the server and storage equipment is the core of network data, is the cornerstone of business development, then the server hard disk is the core of the Data warehouse, all the user data and software are stored in this , it is clear that security, stability for the server hard disk is how important.

At present, the server hard disk according to the different ports, mainly SCSI, SAS and SATA, and several other, and SATA hard disk is widely used in desktop computer (PC) hard disk, while some low-end servers to save costs also have the choice of such interface products, and market mainstream server equipment, Mainly used SCSI and SAS hard drive, and mostly SAS.

Compared to PC hard disk, what are the advantages or characteristics of the server hard disk? summed up mainly in the following four points, server hard disk data read and write faster, more reliable, the use of SCSI or SAS interface and support hot-swappable technology.

• Faster Speed: The server uses the hard disk speed faster, 10000 RPM per minute (such as SAS hard drive common speed is: 15000 rpm), and configure a large back-write cache;

• High reliability: The server's hard drive needs to be run 24x7, with a large amount of data being repeatedly read and written. Server hard disk manufacturers to ensure data security through their own unique technology;

· SCSI or SAS interface: The server uses the disk array card more, obtains the bigger storage capacity, the more flexible array plan, guarantees the server data security and the more efficient data throughput;

• Support Hot-swappable: Hard drive support hot-swappable technology is important for 24-hour running of the server. When the server non-stop or a piece of hard disk damage, unplug or insert a hard drive, the operating system automatically recognize the hard drive changes, as much as possible to reduce data loss.

Although the server hard disk in the high reliability of a lot of effort, than our common PC with the hard disk has an absolute advantage, but as other devices like "hardware failure is inevitable." And as the most direct and final data part, hard disk is sometimes said to be the lifeblood of a company, especially for research and development and design enterprises, if the data or research and development results due to hard disk damage and lost, will cause incalculable loss to the enterprise. Therefore, enterprises in the purchase of products before the best plan is the best policy.

Considering the overall cost, the after-sale service of the server, storage, switch and hard disk of the enterprise becomes the key of the future operation, which can save the cost and ensure the safe, stable and efficient operation of the platform. Therefore, the purchase of products with good after-sales service is the most effective way to relieve the problem of IT managers in the later operation and maintenance.

How CIOs choose Servers, storage, and other devices

Product after-sales service has a lot of details, so also need IT manager attention. We use a real case (cool disk) to let you know in the purchase of servers, storage and other IT equipment when the enterprise users should pay attention to the place.

Cool disk: Founded in August 2010, on-line one year after the registered user volume that is more than tens of millions, is the fastest growing personal cloud storage services company. By the famous angel investor Shire Investment, March 2011 completes a Round 5 million dollars financing, October 2011 completes B round 20 million US dollar financing.

"Cool disk for the server's I/O (input and output capabilities) and the stability of the disk requirements are relatively high." At the beginning of the procurement server, we chose a variety of servers, and even tried to DIY server according to the type of business. But we found that Dell servers were easy to pass in the same-tier, same-price server disk stress tests. After the order, Dell shipped quickly, and the machine has been debugged, by Dell Professional staff directly to our designated room. Machine to the engine room, we through the remote management card in 35 minutes the machine ready, immediately put into use. "Cool Disk founder and CEO Guzhi also pointed out," for the Enterprise operational dimension, the server after-sales service is very important. Because of the uniqueness of cloud storage services, the bad disk rate is a little higher than other industries. That means we have a hard drive error every once in a while. If you are using a Dell server, Dell can give you a swap every day. Dell also has a number of software services, such as remote management cards, which are also very good to use. ”

As the cool disk founder Guzhi said, servers, storage and switches, and even hard disk network equipment is not once and for all, regardless of how manufacturers promise to reworks the product before the low, or even 0 fault guarantee, but the after-sale problem still deserves attention. Therefore, in order to avoid the loss of the most effective measures is to choose a good after-sales service products provider.

Server hard drive you know and don't know

When it comes to hardware failure, enterprise loss, it engine room in addition to server downtime, server, storage and other equipment hard disk error, data can not be normal reading and writing problems to mention. The following are the reasons why the hard disk is damaged, the data cannot be read or lost:

1. Server equipment upgrades, replace the large-capacity hard drive, resulting in the motherboard can not match;

2. The hard disk is in read and write state, server, storage power suddenly interrupted;

3. The hard disk is in read and write state, subject to a larger vibration, so that the head and disc impact, resulting in damage;

4. The working environment temperature too high or too low will make the crystal oscillator clock frequency change, so that the hard drive in the abnormal working state, easy to damage.

Enterprise Server hard disk damage or data loss, generally by the product manufacturer to provide hard disk replacement or data recovery services, but the manufacturer does not guarantee that all data on the enterprise hard disk will be restored. Therefore, enterprises in the selection of good servers, good after-sale, but also the data should be done real-time backup and recovery solutions, so as to minimize losses.

Last September, Enet server channel reporter for the domestic market three major server manufacturers Dell, HP and Lenovo after the after-sales situation, from a multidimensional visit, the final results show that Dell offers the best service.

Dell Server after sale in addition to online support (24 hours * 7 days), telephone support (24 hours * 7 days), mail support and online repair, Dell also provides server extension program and "Keep your hard drive service", so that it builders or managers more assured.

Dell "Keep your hard drive" allows the user to obtain replacement and replacement of the hard drive under the warranty term, essentially ensuring the enterprise's data information security. The main advantages of the performance are:

• Higher security: Enterprise sensitive data and hard drives remain within the control of IT management. Retaining the actual ownership of a failed hard drive is an effective way to ensure that classified data, proprietary data, or sensitive data are safe and reliable.

• Full Data control: through internal retention of the failed hard drive, the user can decide the method and time of disposing data according to the actual situation. It is no longer difficult to track failed hard drives during transportation.

• Comply with regulatory requirements: helps companies comply with existing data privacy regulations and internal company policies by ensuring that sensitive information on the hard drive is secure and reliable.

• Reduce enterprise risk: proper control/disposal of sensitive data helps to prevent potential exposure to customer confidential data or intellectual property, thereby reducing the risk of costly civil liability.

Dell Server warranty scheme and charges: 1 years next business day door-to-door service (400.14 yuan), 2 years next man-days door-to-door service (650.52 yuan), 1 years next business day onsite service +1 years Accidental damage protection (470.34 yuan), 2 years next man-days onsite service +2 years Accidental damage protection ( 740.61 yuan).

Data, the methodology of Enterprise's future transformation

Global Data total breakthrough ZB level, marking that we have entered the early days of large data, and the face of explosive growth in the vast number of data, how to retrieve, manage, analyze and archive high value data in a reasonable time will become the methodology of the future transformation of enterprises.

Data as the only basis for business transformation in the future, direct storage media servers, storage hard disk stability, security, more enterprises need to pay attention to.
