O flash permitiu que tecnologias de efici\u00eancia de armazenamento, como compacta\u00e7\u00e3o, desduplica\u00e7\u00e3o e outras, fossem usadas em ambientes de aplicativos corporativos com impacto m\u00ednimo ou nenhum impacto no desempenho e<\/em> melhorasse significativamente a efici\u00eancia de TB\/watt. Os \u00edndices de redu\u00e7\u00e3o de dados (DRRs, Data Reduction Ratios) resultantes variar\u00e3o, e muitos fornecedores oferecer\u00e3o \u201cgarantias\u201d que conseguir\u00e3o. Se, no uso real, um cliente n\u00e3o conseguir isso, o fornecedor cumprir\u00e1 sua promessa dando ao cliente capacidade de armazenamento \u201cgratuita\u201d para alcan\u00e7\u00e1-lo.\u00a0<\/p>\n\n\n\n

Se voc\u00ea n\u00e3o pensar muito nisso, parece um neg\u00f3cio justo o suficiente. Mas vamos dar uma olhada.<\/p>\n\n\n\n

Garantias de DRR de desembalagem<\/strong><\/h2>\n\n\n\n

Os DRRs variam dependendo de aplicativos, tipos de dados, fluxos de trabalho e casos de uso. Para ambientes corporativos, n\u00e3o \u00e9 incomum atingir DRRs entre 2:1 e 5:1. Ambientes de backup que armazenam muitos dos mesmos dados dia ap\u00f3s dia podem, muitas vezes, alcan\u00e7ar DRRs facilmente dez vezes mais. Isso permite que as empresas comprem menos capacidade de armazenamento bruto para atender a qualquer requisito espec\u00edfico.\u00a0<\/p>\n\n\n\n

No entanto, alguns fornecedores n\u00e3o testam o impacto de suas tecnologias de efici\u00eancia de armazenamento em uma determinada carga de trabalho antecipadamente antes de oferecer uma garantia. O pensamento do fornecedor \u00e9 que um DRR alto (e, portanto, uma classifica\u00e7\u00e3o alta de \u201cefici\u00eancia\u201d) pode influenciar a escolha de um fornecedor de armazenamento espec\u00edfico. Esse acordo de milh\u00f5es de d\u00f3lares vale o custo de alguns discos extras se eles n\u00e3o cumprirem o compromisso de DRR.\u00a0<\/p>\n\n\n\n

Embora isso seja verdade para o fornecedor, e quanto ao ponto de vista do cliente?\u00a0<\/p>\n\n\n\n

Como as garantias de DRR perdidas realmente afetam um cliente<\/strong><\/h2>\n\n\n\n

Se um fornecedor quase n\u00e3o atingir a meta de DRR e precisar fornecer apenas uma ou duas SSDs, provavelmente n\u00e3o \u00e9 um problema. Mas em configura\u00e7\u00f5es maiores de v\u00e1rios PB, onde a economia de DRR significa mais, perder a meta em apenas 10% pode significar que muitas SSDs precisam ser adicionadas. Quantos? Para acomodar esses dispositivos extras, voc\u00ea tamb\u00e9m precisa de controladores e gabinetes adicionais? Eles tamb\u00e9m s\u00e3o gratuitos? Qual \u00e9 o impacto sobre o consumo de energia e espa\u00e7o em rack? Se uma decis\u00e3o de compra de armazenamento foi tomada com base em m\u00e9tricas como TB\/watt, TB\/U e\/ou conte\u00fado de carbono incorporado (coCO2e de fabrica\u00e7\u00e3o, descarte de lixo eletr\u00f4nico<\/a>), o que toda essa engrenagem \u201cgratuita\u201d faz para esse c\u00e1lculo? E se a DRR real fosse conhecida antecipadamente, a mesma decis\u00e3o de armazenamento teria sido tomada?\u00a0<\/p>\n\n\n\n

Para alguns mercados, como o federal dos EUA, os clientes n\u00e3o t\u00eam permiss\u00e3o para aceitar equipamentos \u201cgratuitos\u201d, como SSDs, de fornecedores. Nesse caso, como um fornecedor cumpre sua promessa de DRR se n\u00e3o a cumprir?<\/p>\n\n\n\n

Garanta que seja relevante para seu ambiente e teste seus fluxos de trabalho<\/strong><\/h2>\n\n\n\n

O que faz parte do \u201cc\u00e1lculo de efici\u00eancia de armazenamento\u201d de um fornecedor? Isso provavelmente inclui compacta\u00e7\u00e3o e desduplica\u00e7\u00e3o, e pode incluir outras tecnologias, como provisionamento thin e snapshots compactos. Voc\u00ea deve garantir que cada uma dessas tecnologias de efici\u00eancia de armazenamento seja compat\u00edvel com seu ambiente antes de fazer login.<\/p>\n\n\n\n

Por exemplo, se voc\u00ea tiver ambientes de arquivo ou SQL, talvez n\u00e3o esteja usando especificamente provisionamento thin. Se voc\u00ea estiver usando snapshots, seu uso produzir\u00e1 o mesmo tipo de economia de espa\u00e7o que o fornecedor assume no c\u00e1lculo da efici\u00eancia de armazenamento? Voc\u00ea est\u00e1 criptografando no aplicativo? Isso pode invalidar o uso de tecnologias de efici\u00eancia do lado do armazenamento.\u00a0<\/p>\n\n\n\n

Depois, teste as tecnologias de efici\u00eancia de armazenamento de um fornecedor com rela\u00e7\u00e3o aos seus aplicativos, dados e fluxos de trabalho reais antecipadamente. Se um fornecedor n\u00e3o oferecer isso como op\u00e7\u00e3o, provavelmente \u00e9 um sinal de alerta. Eu tamb\u00e9m estaria c\u00e9tico sobre qualquer promessa inicial sobre DRRs que n\u00e3o exijam nenhum teste real, pois os DRRs variar\u00e3o com base em fatores que n\u00e3o t\u00eam nada a ver com as tecnologias de efici\u00eancia de armazenamento de um fornecedor.\u00a0<\/p>\n\n\n\n

N\u00e3o compre um porco em um poke<\/strong><\/h2>\n\n\n\n

Em geral, os p\u00e2nicos dos fornecedores em torno de DRRs e tecnologias de efici\u00eancia de armazenamento est\u00e3o fazendo com que mais empresas questionem pelo menos a veracidade das promessas feitas antes de uma venda. Alguns querem apenas ofertas de fornecedores sem suposi\u00e7\u00f5es de efici\u00eancia de armazenamento. Isso coloca em desvantagem os fornecedores que realmente conseguem<\/em> atender \u00e0s suas solicita\u00e7\u00f5es de efici\u00eancia de armazenamento. Ela tamb\u00e9m prejudica os clientes que poderiam ter conseguido comprar um kit muito menor com custos menores de infraestrutura de armazenamento, consumo de energia e espa\u00e7o em rack e conte\u00fado de carbono incorporado.<\/p>\n\n\n\n

N\u00e3o \u00e9 nada ruim se um fornecedor puder dizer qual \u00e9 a DRR m\u00e9dia em toda a base instalada e, por todos os meios, voc\u00ea deve olhar para isso. Mas voc\u00ea n\u00e3o pode superar a avalia\u00e7\u00e3o real em rela\u00e7\u00e3o ao seu ambiente de aplicativo. Qualquer coisa menor significa que voc\u00ea pode estar comprando um porco em um poke<\/a>.<\/p>\n\n\n\n

Embora muitos em nosso espa\u00e7o ainda estejam adicionando camadas de gerenciamento a um portf\u00f3lio fragmentado de infraestrutura antiga, estamos construindo uma camada de intelig\u00eancia de dados em uma base Evergreen. O Everpure resolveu o armazenamento convencional e as opera\u00e7\u00f5es unificadas. Agora, com o 1touch, resolveremos\u00a0 o gerenciamento de dados no n\u00edvel dos dados em si, ajudando as organiza\u00e7\u00f5es a controlar a complexidade dos dados e transform\u00e1-los em conhecimento valioso, para que elas, e n\u00e3o sua AI, controlem seu destino.<\/a><\/p>\n<\/div>\n<\/div>\n\n\n\n
