Configuration as RAID and iSCSI in Synology DS1010

[Zeppelin]

In our rush of speed, we set the three built-in hard drives of the type WD1600AAJS-0 as RAID 0 one. In a production environment would, however, a RAID -Choose Version, the loss protection increases - but that no backup replaced to a data loss due to virus attack to prevent such. How and what RAID variants can be migrated without any data loss later, explains the surface using a function of management in detail. On the thus obtained volume also we set up a iSCSI target, because in contrast to CIFS and NFS, the file-oriented work, the data here, block-oriented transfers, which, as our tests showed in the past, not only in the theory promises a faster transportation. In addition, an iSCSI drive, up to ten iSCSI target support for the client accessing a kind of transparent hard drive, like a physical disk is accessed in the computer. In this way, applications can also be used, which will refuse to work with network drives. Allowed earlier Synology iSCSI implementations are not competing requests of two computers on an iSCSI target, it is possible today. Otherwise, the implementation of the Disk Station is more easily turned out, with, however security features such as CHAP authentication available. The iSCSI support on the client side is on current Windows versions such as Vista or Windows 7 no longer an issue.

All programs were on the client side on a computer with quad-core CPU and 4 GB of RAM running Windows 7 starts. Long faces were there then, when the first results were available: with read rates of up to 56 MB / s and write data up to 100 MByte / s from the measured values were far from the promises Synology advertising. Even without the above-mentioned link aggregation, the DS1010 + write values to the 108 MByte / s, and achieve read rates of over 110 Mbytes / sec. Even with iSCSI collapsed while Atto benchmark achieved only a small improvement: the values could write 105 Mbit / s will be increased to around. The read rates were however not go over 56 MByte / s, but these values were then also measured at different values for the transfer size. Repeated attempts did not yield better results. Disappointing were the numbers that Intel's NAS benchmark provided. If using CIFS, the maximum write rate was around 77 MByte / s. Were read data at up to 44 MByte / s. With iSCSI, the results were writing about 100 MByte / s can be improved. When combined read spat out of the test rates of up to 70 MB / sec.

If Synology wasted in such way as the big drum with unrealistic values move shamelessly? A request from the manufacturer in Taiwan provided the insight that the problem is not unknown there. Synology Manager Edward Lin explains the phenomenon so that we were to analyze the data packets from Intel's NAS Performance Toolkit found that the software uses traffic patterns to those of Iozone similar. So, write a byte, the space for one byte is reserved. I suspect that here is a simple C library for standard I / O commands is used to. And with such a time is now, readers rate of a single-threaded program to 60 to 70 MB / s limit.

The performance of the write and read access is on a NAS , which according to the manufacturer so more servers to be, but only half the battle. What is the impact the DS1010 + as an application server with the dual core atom and a GB of RAM? Previously, from Synology PowerPC or ARM processors usual, the clock speeds of up to 1.2 GHz and usually ran with up to 512 MB of RAM had to. The difference for the DS1010 + is practically tangible. Thus, the will to work with Ajax -based user interface much faster than with an older DS207 +. The power reserves are also evident when the Disk Station to photo albums and web application creates thumbnails or videos Photo Station for the integrated video player in the Flash format. Here was the little DS207 + with larger amounts of data very busy days time, so the current test candidate manages this task in a manageable time. In other PHP applications like WordPress, Joomla, Typo3 or a mail server with the Synology mail package is the current model is not as fast from the breath.

Who wants to install their own Linux-based applications using the package management system ipkg (Itsy Package Management System), must ensure that he selects the Intel Atom-suitable packaging system. Synology used because only recently Intel CPUs, the user must expect that one or the other application is not compiled for the platform. A detailed explanation of the Integration of third-party applications and the procedure for compiling the manufacturer as a PDF file published. Otherwise available to the DS1010 + as the other Synology products with the current DSM 2.3 out of house on the most important enterprise features like Firewall , Active Directory, Web and print servers , file servers, monitoring via IP camera, backup solution, SNMP and print server. Overall drive Synology here again a mix of applications for the business audience and consumer applications (such as iTunes server Station or audio), as we of the previous tests (DS209 + II or III. DS508) were used. In this case, however, learned some applications, a fine-tuning to improve performance and usability.
