PMC展示分层存储解决方案
龙源期刊网 PMC展示分层存储解决方案作者：来源：《中国信息化周报》2014年第10期近日，PMC在2014 CeBIT上展出其带有maxCache Plus分层软件的Adaptec by PMC 8系列RAID卡及基于12Gb/s SAS HBA的软件定义存储解决方案。
PMC演示了其研发的带有零维护缓存保护和maxCache Plus的8系列12Gb/s SAS RAID卡。
演示中展示了一款由12Gb/s SAS SSD和HDD组成的两层存储解决方案。
其中性能分层是采用希捷的1200 12Gb/s SAS SSD，而通过maxCache Plus驱动SSD加速第二层的希捷企业级Constellation.2 SATA HDD。
Adaptec maxCache Plus的分层功能及冗余存储池均由Adaptec的maxView Storage Manager软件进行管理。
8系列中的maxCache Plus，在管理与其连接的PCIe闪存卡、SSD以及HDD的同时，可以实现对不同存储介质的分层，以确保关键应用和热数据优先使用高性能的存储介质。
另外，PMC还演示了基于Windows Storage Spaces软件定义存储解决方案的带冗余的高可用性集群。
该集群由Adaptec by PMC 12Gb/s SAS HBA驱动，通过PMC的12Gb/s SAS扩展器相连。
演示中，Chenbro的一款外置高密度存储解决方案将采用一款基于PMC的12Gb/s RoC 技术的原型HBA解决方案与两个服务器节点相连。
PMC的此项技术在单个板卡上结合了配备基本启动服务器系统的RAID功能以及完整的HBA功能。

adaptec Adaptec 6系列和5Z系列 RAID控制卡的零维护缓存保护
零维护缓存保护简报降低数据中心运营成本，最大限度保护缓存数据产品要点低运营成本– 没有电池相关的安装、监控、维护、弃置或者更换成本停电情况下不会丢失数据– 取代锂电池零维护缓存保护– 无需监测电池充电情况– 更换电池过程中不需要关闭系统– 无限期地保护数据 -“在电池电量耗尽之前”不需要急于重启系统– 保存数据长达数年之久RAID缓存即时保护– 充电只需要几分钟时间，而不是几小时– 环境优化RAID性能环保– 无毒电池废弃处理– 配合Adaptec智能电源管理功能打造行业“最绿色”解决方案- 遵从简化的 IATA 规则完全集成在5Z系列RAID控制上并作为6系列的附件套件IDC预计，在四年时间内一步IT设备的运营成本将增长到原始采购成本的4倍。
Adaptec 6系列和5Z系列RAID控制卡采用了零维护缓存保护（Zero-Maintenance CacheProtection，ZMCP）功能，最大限度保护缓存数据，大幅削减成本并减少了复杂、杂乱和昂贵的锂电池对环境的影响，同时提高了缓存保护和缓存性能。
为什么你需要缓存保护随着用户持续关注针对快速增加的数据集进行的容量利用率优化，RAID 5和RAID 6在企业级存储系统中的运用继续增长着。
然而，除非启用了所有可用缓存，否则系统无法实现最佳性能。
不过，启用控制卡缓存之后，数据被保存在控制卡的内存中，并有可能在系统断电的情况下丢失。
防止这种情况发生的最常见保护措施就是使用一个直接安装在控制卡上的电池备份单元（BBU）来备份控制卡缓存。
这种电池是维护板载缓存数据，直到恢复对电池备份单元的供电。
电池备份单元的第二个使用方法就是配合Adaptec 6系列、5Z系列、5系列和2系列RAID控制卡产品系列所提供的Adaptec智能电源管理功能（Intelligent Power Management）。
为了让控制卡降低硬盘转速或者完全停转，硬盘中必须是没有任何I/O活动的。

Device summary ReferenceOrder code ST25DV-DISCOVERY ST25DV-DISCOVERYDescription ST25DV-DISCOVERY 2/4DocID029577 Rev 21 DescriptionThe ST25DV-DISCOVERY is a demonstration kit to evaluate the features and capabilities ofthe ST25DV series. It is based on the NFC ST25DV04K device embedded on a daughtercard using a Class 5 antenna and a STM32 processor driving a mother board. A dedicatedsoftware stored in the Flash memory is provided.The ST25DX_Discovery_Mboard is available in two versions. The demonstration editionincludes all of the standard edition features with Wi-Fi ®, and BLE (Bluetooth Low Energy)modules to demonstrate various connectivity use cases. The standard edition is used toachieve the demonstration edition features.The ST25DV04K device is a dynamic NFC/RFID tag IC with a dual interface. It embeds a4 Kbits EEPROM memory. It can be operated from an I 2C interface, or by a 13.56 MHzRFID reader, or by a NFC phone. The ST25DV04K Class 5 antenna daughter card, includedin the kit, can be replaced by Class 1 or Class 6 antennas. For this purpose an ST25DVantennas bundle is available for ordering. Its references are available on the ST web site.The ST25DV I 2C interface uses a two-wire serial interface, consisting of a bidirectional dataline and a clock line. The I 2C two-wire serial interface behaves as a slave in the I 2Cprotocol. The RF protocol is compatible with ISO/IEC 15693 and NFC Forum Type 5 tag contactless interface.The boards are powered through the USB connectors.The ST25DV-DISCOVERY (MB1283 & MB1285) schematics, BOM, gerber files, drivers andfirmware sources can be downloaded from .Figure 2.
