Key points to note on these N8103-150 NEC Raid Controllers:-

N8103-149/150/151/160 RAID controllers, which support NEC Express5800 Server Series, employ DDR3 Memory for cache memory and a dual core IO processor from LSI.

Compared to existing RAID controllers with RAID Access functions, sequential reading performance is doubled and sequential writing is improved 1.6 times. (Tested and validated by NEC)

MegaRAID® CacheCade® enhances RAID performance by allocating a Solid State Drive (SSD) as cache memory for the RAID controller.

  •   ::  N8103-149 is the most suitable RAID controller for customers building a small scale RAID configuration of RAID 0, 1, and 10.
  •   ::  N8103-150 and N8103-151 are RAID controllers that support all general RAID levels which use RAID 0, 1, 5, 6, 10, 50, and 60.
  •   ::  N8103-160 is a RAID controller for connecting external storage, and supports RAID 0, 1, 5, 6, 10, 50, and 60.

MegaRAID CacheCade is a function which improves the performance of the random read process, using the SSD as a read cache.

Normally, SSD performs better than HDD, but the cost of implementation per device is high. Cost/performance may be prohibitive when building a RAID system with SSD.

When the MegaRAID CacheCade uses the SSD as a cache for the RAID controller, the RAID system on the HDD can improve performance while keeping the cost to a minimum. 

MegaRAID CacheCade is enabled by combining the N8103-156 MegaRAID CacheCade with the N8103-151 RAID controller (1GB, RAID 0/1/5/6). N8103-156 comes with a hardware key that enables MegaRAID CacheCade. Use the key to enable MegaRAID CacheCade and implement to N8103-151. A BTO shipment includes a hardware key.

It is possible to use a MegaRAID CacheCade, regardless of whether the OS is Windows or Linux, or using VMware.

The RAID Controllers have the following new features:

  •   ::  Employ a dual core IO processor as the RAID computing processor (equipped with a LSISAS2208 chip).
  •   ::  Employ DDR3 memory as a cache memory. Equipped with a cache capacity of 512MB or 1GB (existing products have 256MB or 512MB cache).
  •   ::  Complied with MegaRAID CacheCade, which improves RAID performance by allocating the SSD as RAID cache memory (refer to section 4).
  •   ::  Support SAS SSD and SATA Hard Disk Drive (HDD), which enables a transfer rate of 6Gb/s.
  •   ::  Support RAID 60. (Also supports the RAID system management utility Universal RAID Utility).
  •   ::  ® Reduce power consumption by employing the HDD power management function (Manage Powersave), which controls the power supply to the spare disk.
  •   ::  Gather information about the HDD and operating RAID controller, by EXPRESSSCOPE ® Engine 3 (a function of NEC Server Management).
  •   ::  The RAID controllers employ an LSISAS2208 chip from LSI as the RAID computing processor, and are equipped with 512MB or 1GB cache capacity (existing products [N8103-129/130/134/135] have 256MB or 512MB cache).
  •   ::  The RAID controller employs a HDD power management function (Manage Powersave), which enables a spare disk to run in a power save mode when the system is operating normally. This reduces power consumption.
  •  
  • In general, a spare disk is only required in case of failures and if the system is operating normally; it is not necessary to have it operating continuously.
  •  
  •   ::  SATA HDD and SAS HDD consume 5-10W when in standby mode. If 3 spare disks are in the system, 15W could be saved by utilizing the power management function.
  •   ::  As the spare disk is checked periodically by patrol read (a function to check for errors on the entire hard disk drive), errors on the hard disk can be detected early.
  •   ::  The HDD power management function is disabled when shipped. The HDD power management control function must be set to ‘enabled’ from the RAID system management utility “Universal RAID Utility” or the server management utility “ESMPRO/Server Manager."
  •   ::  It is possible to configure the transition time to power saving mode. Use the CLI the same way on Linux.
