如果說(shuō)服務(wù)器是網(wǎng)絡(luò)數(shù)據(jù)的重要，那么服務(wù)器硬盤就是這個(gè)重要的數(shù)據(jù)倉(cāng)庫(kù)，所有的軟件和用戶數(shù)據(jù)都存儲(chǔ)在這里。對(duì)用戶來(lái)說(shuō)，儲(chǔ)存在服務(wù)器上的硬盤數(shù)據(jù)是關(guān)鍵寶貴的，因此硬盤的可靠性是非常重要的。為了使硬盤能夠適應(yīng)大數(shù)據(jù)量、超長(zhǎng)工作時(shí)間的工作環(huán)境，服務(wù)器一般采用高速、穩(wěn)定、安全的SCSI硬盤。硬盤技術(shù)：硬盤接口是硬盤與主機(jī)系統(tǒng)間的連接部件，作用是在硬盤緩存和主機(jī)內(nèi)存之間傳輸數(shù)據(jù)。不同的硬盤接口決定著硬盤與計(jì)算機(jī)之間的連接速度，在整個(gè)系統(tǒng)中，硬盤接口的優(yōu)劣直接影響著程序運(yùn)行快慢和系統(tǒng)性能好壞。服務(wù)器常用硬盤為三種：一是SATA：串行ATA總線、二是SCSI：小型電腦輸入輸出接口、三是SAS：希捷研究出來(lái)的取代SCSI技術(shù)的接口。接口速度是 SAS〉SCSI〉SATA。以上均采用串行技術(shù)以獲得更高的傳輸速度，并通過(guò)縮短連結(jié)線改善內(nèi)部空間等。SAS是并行SCSI接口之后開(kāi)發(fā)出的全新接口。此接口的設(shè)計(jì)改善存儲(chǔ)系統(tǒng)的效能、可用性和擴(kuò)充性，支持熱插拔，可向下兼容SATA及部分SCSI設(shè)備，并逐步取代SCSI。相比PC硬盤,服務(wù)器硬盤一般具有速度快、可靠性高及熱插拔等。江蘇超頻服務(wù)器質(zhì)量推薦證券公司的營(yíng)業(yè)部機(jī)房配置如何搭建？</p><div

主要有幾個(gè)部分：**處理器、內(nèi)存、芯片組、I/O總線、I/O設(shè)備、電源、機(jī)箱和相關(guān)軟件。這也成了我們選購(gòu)一臺(tái)服務(wù)器時(shí)所主要關(guān)注的指標(biāo)。對(duì)于一臺(tái)服務(wù)器來(lái)講，服務(wù)器的性能設(shè)計(jì)目標(biāo)是如何平衡各部分的性能，使整個(gè)系統(tǒng)的性能達(dá)到比較好。如果一臺(tái)服務(wù)器有每秒處理1000個(gè)服務(wù)請(qǐng)求的能力，但網(wǎng)卡只能接受200個(gè)請(qǐng)求，而硬盤只能負(fù)擔(dān)150個(gè)，而各種總線的負(fù)載能力*能承擔(dān)100個(gè)請(qǐng)求的話，那這臺(tái)服務(wù)器得處理能力只能是100個(gè)請(qǐng)求/秒，有超過(guò)80%的處理器計(jì)算能力浪費(fèi)了。所以設(shè)計(jì)一個(gè)好服務(wù)器的**終目的就是通過(guò)平衡各方面的性能，使得各部分配合得當(dāng)，并能夠充分發(fā)揮能力。我們可以從這幾個(gè)方面來(lái)衡量服務(wù)器是否達(dá)到了其設(shè)計(jì)目的;R：Reliability——可靠性;A：Availability——可用性;S：Scalability——可擴(kuò)展性;U：Usability——性;MManageability——可管理性，即服務(wù)器的RASUM衡量標(biāo)準(zhǔn)。 </p> <p> <br /> </p><p> 低延時(shí)交易（Low-latency trading）是算法交易的一個(gè)分支，可以定義為資本市場(chǎng)參與者對(duì)市場(chǎng)事件進(jìn)行更快速的反應(yīng)，利用極其細(xì)微的反應(yīng)時(shí)差，來(lái)獲得更多盈利的一種交易方法。延遲是計(jì)算機(jī)系統(tǒng)接收到一個(gè)事件刺激，到產(chǎn)生響應(yīng)之間的時(shí)間間隔。對(duì)于對(duì)金融機(jī)構(gòu)而言，這個(gè)可以是客戶端輸入報(bào)，可以是接收到市場(chǎng)行情數(shù)據(jù)發(fā)布，可以是接收到報(bào)單的確認(rèn)返回或成交回報(bào)。高頻交易（High-frequency）是低延時(shí)交易中的一個(gè)類別。低延時(shí)交易還可以包括其他的、同樣具有高速屬性的交易方法。低延遲交易要求整個(gè)交易鏈條上的所有環(huán)節(jié)，都盡量縮短時(shí)間間隔。對(duì)低延遲交易技術(shù)的掌握程度也是專業(yè)機(jī)構(gòu)與普通投資者的差距所在。從交易系統(tǒng)的層面來(lái)看，交易延遲主要包括網(wǎng)絡(luò)延遲、協(xié)議延遲、操作系統(tǒng)延遲、應(yīng)用延遲等幾類。

按照多數(shù)人的理解，一般人概念里的高頻交易系統(tǒng)是這樣的：交易指令完全由電腦發(fā)送，對(duì)市場(chǎng)數(shù)據(jù)的響應(yīng)延時(shí)在微秒級(jí)（VBA退散）。系統(tǒng)由**的軟硬件組成，研發(fā)時(shí)需要大量計(jì)算機(jī)**級(jí)的工作（散戶隨便編個(gè)小程序退散）。系統(tǒng)的硬件需要放在離交易所主機(jī)很近的位置上，所謂 co-location。并且得到專門的準(zhǔn)入許可證，交易指令直接發(fā)送至交易所（而不是通過(guò)券商中轉(zhuǎn)）。符合這三點(diǎn)的，就可以叫做高頻交易系統(tǒng)。 </p> <p> <p> 高頻交易的特征 </p> <p> 1，高頻交易都是由計(jì)算機(jī)自動(dòng)完成的程序化交易； </p> <p> 2，高頻交易的交易量巨大； </p> <p> 3，高頻交易的持倉(cāng)時(shí)間很短，日內(nèi)交易次數(shù)很多； </p> <p> 4，高頻交易每筆收益率很低，但是總體收益穩(wěn)定。 </p> 正規(guī)靠譜的服務(wù)器怎么選擇？上海思鴻有供應(yīng)。江西超頻服務(wù)器哪家好</p><p
