The future SSD is here—PCIe/NVMe boosts Ceph performance

first_imgCeph shows a strong trend as opensource scale out storage adoption in worldwide market and we are observing strong customer requirements for high performance storage, from must-have SSD as Journal and caching to all SSD flash solutions, ranging from CSP, FSI, Telecom, HPC/government etc to OEM/ODM.On the weekend of October 18, as the top-level Ceph community and industry conference on Ceph technology in china, themed “Ceph: The future of storage”, 2015 Shanghai Ceph day attracted 33 companies and over 140 developers, IT experts, academic leaders, business and technical managers etc, Intel delivered 1 opening and 4 key technical presentations along with Redhat, Suse, Mellanox, H3C and other industry partners delivered 10 other technical sessions.On behalf of Intel, I along with two other Intel engineers presented “SSD/NVM technology Boosting Ceph performance”, see attached pdf, we propose first ever all SSD Ceph configuration, combination of 1x NVMe SSD (Intel P3700 800GB) as Journal + 4 x Low cost high capacity SATA SSD (Intel S3510 1.6TB) as OSD data drives, this configuration has dramatically increased random write performance ~100K iops (4 node cluster), which is >32x compares to SSD as journal + 40 HDDs configuration, or in order to reach 100K iops, you need total of 1300 HDDs, this has not counted power consumption, HDD fail rate, space, maintenance cost etc, you can image the total cost ownership (TCO) for using all SSD would be dramatically lower than HDDs…We also presented Intel iCAS + Intel PCIe/NVMe SSD P3700 accelerates Ceph performance.In addition, I propose three Ceph configurations: 1)standard/good Ceph configuration, PCIe/NVMe SSD as Journal and caching, plus HDDs as data drives, the ratio is 1:16/20, example is 1 x Intel P3700 800GB SSD + 20 HDDs, P3700 as both Journal and caching (with Intel iCAS), 2)advance/better configuration: NVMe/PCIe SSD as Journal + large capacity SATA SSDs, example is above 1xP3700 + 4 S3510; 3)the best performance configuration will be ALL NVMe/PCIe SSDs, example is 6xP3700 2TB SSD per node.last_img read more

‘India is only beginning to develop its industry’

But how does the country rate in the eyes of International observers who have had occasion to watch her performance at close hand, either as representatives of their country in missions here, or participants in industrial fairs? India Today interviewed a number of delegates attending the India International Trade Fair currently on in New Delhi. Their views:Moustafa Al-Bitar, 49, and Husni Al-Diab, 39, of Syria, spoke of India’s reputation as a leader of developing countries. Both took their degree in law at Damascus University. Al-Bitar is a director of International Relations in Syria’s Ministry of Economy and Foreign Trade while Al-Diab is head of the Department of Monetary and Banking Affairs in the same ministry.Both are familiar with India’s technical expertise and know-how and maintained that Syria and India were in the same boat, as far as industrial development was concerned. Al-Bitar thinks highly of Indian textile and machine tools, “comparable to the world’s best”, he says. The fair, according to him, would give a further boost to the existing trade relations between India and Syria.Popular Pavilion: Andrzej Wojtkowiak, 35, is the manager of the Finance Department of Impexmetal, Warsaw, Poland. A statistics graduate, he is in charge of foreign exchange transactions of his country’s metal trade. He knew very little about India before arriving for the fair, and his view of India is still “through the window of a taxi”.advertisementRomanowski: surprised by progress”I think this is a country which is only beginning to develop its industry – I can recognise that your manner of erecting buildings is very simple. I am surprised how you manage without machines,” he says almost admiringly. He thinks India has a very large market for electronic goods and mining and construction expertise. “The future of trade relations between our countries is bright,” he says.The Chinese pavilion is drawing the largest crowds, obviously because it is their first appearance in an Indian fair. The number two man at the pavilion, Mr Han, is a member of the China Council for Promotion of International Trade which has been quite active recently on the world scene. Han, 40, was happy to see so many people coming to his pavilion – “your people are very friendly”, he says, smilingly. About his impression of India as an industrial nation, he said he had not really been able to get round as much as he would have liked.Gisela Romanowski, press officer of the German Democratic Republic (GDR) pavilion, was “astonished” to see how well Indian industry has developed. She is, as any woman would be, fascinated by Indian silk. She has been to quite a few Indian pavilions in the fair and found the items on display “good – at least from a distance”. Romanowski, who also edits GDR’s foreign trade journal, says that the GDR pavilion has transacted good business in the first two weeks. “It remains to be seen how we do by the end of the fair,” she adds, shaking her head.Two Views: This is the first time that Zambia is participating in an Indian trade fair. “Why have you caught me unawares?” asked the Zambian delegate C.N. Chilese, 41, who is an official in his country’s Ministry of Commerce and Trade in Lusaka. “This fair has been a success from the Zambian point of view – we have made useful contacts with various organisations and will be exporting copper wires, cement, lead, zinc and other minerals to India,” he states.Chilese thinks that Indian goods are competitive, particularly the textile and engineering goods, which, according to him, are comparable with the best, including those from Europe. “Your technology is well developed,” he says, “and your people are very hard working.”Blums (left) and Chilese: fruitful tripAivar Blums of Australia is not all praise, however. “Your sporting goods and textiles are of excellent quality but your machine tools and hand tools industry-lacks consistency,” he maintains. Blums, 32, is currently serving as assistant trade commissioner in New Delhi. He has been in India for the last two years and has been impressed by “the depth and width of Indian industry – its ability to produce such diverse items ranging from handlooms to sophisticated computers and aircraft.”He said he had brief discussions with other overseas delegates and felt that the fair has been, on the whole, a success. According to Blums, India has the potential to be one of the world’s major industrial nations in the next decade, “if only she can surmount problems of logistics and power”. To which, one can only add. Amen. advertisementlast_img read more
